"Error: conflicting requests" in centos 8 package installation - centos

I am trying to install the gdal on my centos 8. I tried with following command
sudo yum install gdal
And it through me following error,
Last metadata expiration check: 0:05:58 ago on Sun 10 Jan 2021 10:52:18 PM EST.
Error:
Problem: conflicting requests
- nothing provides libdap.so.25()(64bit) needed by gdal-libs-3.0.4-5.el8.x86_64
- nothing provides libdapclient.so.6()(64bit) needed by gdal-libs-3.0.4-5.el8.x86_64
- nothing provides libdapserver.so.7()(64bit) needed by gdal-libs-3.0.4-5.el8.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
Please, anyone, suggest to me, how to solve this error?

You can enable the powertools repository to solve this issue,
sudo yum install dnf-plugins-core
sudo yum config-manager --set-enabled powertools
Now you can install the gdal by following code,
sudo yum install gdal-devel

Installing PostgreSQL on CentOS 7 (since mid April 2020)

I have a script that I use for installing Postgres 9.6 in a CentOS 7 Docker image. It looks like this:
wget https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-7-x86_64/pgdg-centos96-9.6-3.noarch.rpm
yum install -y -q pgdg-centos96-9.6-3.noarch.rpm epel-release
yum update -y -q
yum install -y -q postgresql96-server sudo
As of mid April 2020, it started failing because https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-7-x86_64/pgdg-centos96-9.6-3.noarch.rpm is no longer available. I understand that the way RPM packages for Postgres are published has changed this month. Can anyone help me find the updated url for the 9.6 rpm package? I have been Googling but can't seem to find it for some reason.
Really appreciate any guidance on this.
The new repository URL is available here: https://www.postgresql.org/download/
Select Redhat/Centos 7
Select version 9.6
Then it shows you how to install the new repository:
yum install https://download.postgresql.org/pub/repos/yum/reporpms/EL-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm

Cannot install Icinga Web 2 on CentOS 8

I have installed Icinga2 on my server, which is running CentOS 8. However, I run into problems when I try and install Icinga Web 2.
When I try and run the command yum -y install icingaweb2 icingacli, CentOS cannot find the packages. The following output is given:
Last metadata expiration check: 0:01:04 ago on Sat 16 Nov 2019 23:22:22 NZDT.
No match for argument: icingaweb2
No match for argument: icingacli
Error: Unable to find a match
It also cannot find the packages centos-release-scl and icingaweb2-selinux.
I've added the Icinga repositories to CentOS manually, including EPEL relase, and they are showing in the yum.repos.d folder. But every time I try and install Icinga Web 2, whether with yum or dnf, I get the same error. I've tried dnf makecache and yum makecache and have updated the packages, but nothing seems to work.
What is going on here?
For install icinga via package management you should add this repo: https://packages.icinga.com/epel/

Why is installing PostGIS 3 on RHEL 8 / CentOS 8 impossible?

I am attempting to install the latest PostGIS 3.0.x on CentOS 8, with no luck.
I don't think anyone is running PostGIS on RHEL 8 or CentOS 8, I can't understand why not. It does not seem possible to install.
I have successfully installed Postgres 12.0 by disabling the RHEL AppStream
Steps I took installing postgres 12 on CentOS 8:
1)
#dnf install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
2)
#dnf --disablerepo AppStream install postgresql12
#dnf --disablerepo AppStream install postgresql12-server
I am attempting now to install PostGIS.
#dnf list --available | grep postgis30
I see that postgis30_96 is the latest offered (as listed below):
postgis30_96.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-client.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-client-debuginfo.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-debuginfo.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-devel.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-docs.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-gui.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-gui-debuginfo.x86_64 3.0.0alpha4-6.rhel8 pgdg96
postgis30_96-utils.x86_64 3.0.0alpha4-6.rhel8 pgdg96
When I try to install with the following command:
#dnf install postgis30_96
I get these errors:
Last metadata expiration check: 1:22:58 ago on Tue 15 Oct 2019 08:25:10 PM UTC.
Error:
Problem: cannot install the best candidate for the job
- nothing provides hdf5 needed by postgis30_96-3.0.0alpha4-6.rhel8.x86_64
- nothing provides xerces-c needed by postgis30_96-3.0.0alpha4-6.rhel8.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
I look for xerces-c, and nothing is returned:
#dnf list --available | grep xerces-c
Where do I get xerces-c to install?
I look to see if hdf5 is available to install (dependency)
#dnf list --available | grep hdf5
and nothing is returned. How do I satisfy these dependencies, so that PostGIS will install?
I goto the hdf5 website, download the source and it's a BIG FAT MESS. The build/install instructions do not work - the code is out of sync with the install instructions.
I check the hdf5 website and find another set of build/install instructions, and they too are out of sync with the latest code base. I don't know which way is up with this project, if it's a zombie project out there on the web, seemingly alive, but nobody's home.
How do I get hdf5 easily onto my system and xerces-c so that nothing existing gets mucked up? I would prefer to install these through any somewhat sanctioned CentOS 8 package repo using dnf.
I can't log this issue on the PostGIS ticket tracking system. Logging a ticket there requires an OSGEO ID, and when I request a 'mantra' to get started, nothing is returned, no response,
OSGEO is yet another zombie project, nobody's home. https://www.osgeo.org/community/getting-started-osgeo/osgeo_userid/
Please respond only if you have actually done this yourself on a CentOS 8 machine or VM, while I appreciate suggestions, pointers or imaginations from others, it pollutes r/postgis reddit with misinformation, non-working solutions, and not only wastes my time with dead ends, but also the time of others.
Someone else inevitably comes along with the same problems and is misguided with these those that are well-intentioned, but provide incorrect or incomplete information.
I had the same problem and finally found the solution. I need postgis25 for postgresql10, so I typed this command
dnf --enablerepo=PowerTools install postgis25_10
The PowerTools repo has the packages from codeready-developer repo, from Redhat CodeReady Studio. It contains a lot of useful tools.
Cannot enable PowerTools for RHEL 8
https://access.redhat.com/discussions/5417621
Remarks: PowerTools is a CentOS repository. On RHEL 8 we have the CodeReady Builder repository!
I am now able to install PostGIS-3 for PostgreSQL-12 on RHEL-8.
Solution:
sudo subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms
dnf install postgis30_12
Summing up the previous answers, these are the commands needed to install PostGIS-3 on CentOS-8:
dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
dnf -qy module disable postgresql
yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
dnf --enablerepo=PowerTools install postgresql12-server postgresql12-contrib postgis30_12
Many of the answers were helpful. To sum up the steps I had to take and errors in the instructions at https://people.planetpostgresql.org/devrim/index.php?/archives/107-Installing-PostGIS-3.1-and-PostgreSQL-13-on-CentOS-8.html
As mentioned by Marcelo, for RHEL use code-ready, not powertools.
As mentioned in this thread, don't mix packages. Run dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
to get the pgdg repo before installing postgres. Then run dnf -qy module disable postgresql if needed then install postgres like sudo dnf install -y postgresql13-server
The command to install epel-repo listed here may not work. Try sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
Get the name of the latest postgis release with this command. sudo dnf list --available | grep postgis3 As mentioned by Nick, the second two digits are your postgres version.
Install postgis sudo dnf -y install postgis3x_xx I repeat, the second two digits are your postgres version.
So, in summary, to install postgres and postgis on my rhel8 sytstem, I ran these commands in this order.
sudo dnf -qy module disable postgresql
sudo dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
sudo dnf install -y postgresql13-server
sudo /usr/pgsql-13/bin/postgresql-13-setup initdb
sudo systemctl enable postgresql-13
sudo systemctl start postgresql-13
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms
sudo dnf -y install postgis31_13
The postgis30_96 packages are for Postgres 9.6. You need postgis30_12 for Postgres 12.
These packages are definitely in the repo, so if your dnf list isn't seeing them, it may be an instance of a known issue in which "yum/dnf refuse to find/install many packages from PGDG repository on RHEL8".
As a workaround, the Postgres Yum Howto recommends this installation procedure:
dnf -y install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
dnf -qy module disable postgresql
dnf install postgresql11-server postgresql11-contrib
Percona Postgresql 13 And Postgis 3.0
https://www.percona.com/doc/percona-repo-config/index.html
dnf remove postgresql
sudo dnf install https://repo.percona.com/yum/percona-release-latest.noarch.rpm
sudo percona-release setup ppg-13
You can refer here:
https://www.percona.com/doc/postgresql/LATEST/installing.html#using-the-rpm-format
sudo dnf module disable postgresql
sudo dnf install percona-postgresql13-server
sudo dnf install percona-pg_repack13
sudo dnf install percona-pgaudit
sudo dnf install percona-pgbackrest
sudo dnf install percona-patroni
sudo dnf install percona-pg-stat-monitor13
sudo dnf install percona-postgresql13-contrib
/usr/pgsql-13/bin/postgresql-13-setup initdb
sudo systemctl start postgresql-13
PostGIS
dnf -y config-manager --set-enabled PowerTools
dnf install -y postgis30_13 postgis30_13-client
What helped me in CentOS container (as a root):
yum -y install dnf-plugins-core && yum config-manager --set-enabled powertools
Installing dnf-plugins-core and enabling powertools.

How to install the perl DateTime module under CentOS8. yum install "perl(DateTime)" worked in CentOS7 but not in 8

There are some Perl modules that could previously be installed with:
yum install "perl(DateTime)"
Under CentOS7. In CentOS8 I get the error:
No match for argument: perl(DateTime)
I have the same problem for perl(Template), perl(YAML::XS), perl(Crypt::Eksblowfish::Bcrypt) and perl(JSON::XS)
I tried searching with:
yum provides *DateTime*
But I can't find anything there either.
perl-DateTime is no longer part of the CentOS 8 base OS. You'll need to enable the PowerTools repository, i.e. as root
# yum config-manager --set-enabled PowerTools
# yum update
# yum repolist
repo id repo name status
...
PowerTools CentOS-8 - PowerTools ...
...
# yum install "perl(DateTime)"
or...
# yum install perl-DateTime
perl(YAML::XS) (AKA perl-YAML-LibYAML) should also be available.
perl(Template) (AKA perl-Template-Toolkit) and perl(Crypt::Eksblowfish::Bcrypt) (AKA perl-Crypt-Eksblowfish) no longer seem to be provided, not even in EPEL8. So you'll have to install them from CPAN.

centos yum fails installing anything or updating system

I am trying to install a package on CentOS, but it throws error when I run the "yum" command. The internet connection is working fine.
I try to yum clean all but problem persist.
Error:
[root#dcos-master3 ~]# yum install ntp
Loaded plugins: fastestmirror
One of the configured repositories failed (Unknown),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Run the command with the repository temporarily disabled
yum --disablerepo=<repoid> ...
4. Disable the repository permanently, so yum won't use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use --enablerepo for temporary usage:
yum-config-manager --disable <repoid>
or
subscription-manager repos --disable=<repoid>
5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
Cannot find a valid baseurl for repo: base/$releasever/x86_64
My yum repolist is the next:

BEFORE TRYING ANY OF THIS, HAVE A BACKUP OF YOUR MACHINE, YOU COULD DAMAGE YOUR OS MORE/COMPLETELY
It seems that your yum variable $releasever is somehow corrupt,
it usually is caused by missing centos-release package on the machine for some obscure reasons.
You can check if you have the package by:
rpm -qi centos-release
You will probably see:
"package centos-release is not installed"
First find out the exact centos version that you have by executing as root:
cat /etc/redhat-release
You will see something like this:
CentOS Linux release 7.3.1611 (Core)
You can fetch the centos-release package from repo by:
wget http://vault.centos.org/centos/7.3.1611/updates/x86_64/Packages/centos-release-7-3.1611.el7.centos.2.5.x86_64.rpm
Now run reinstall centos-release package via rpm:
sudo rpm -Uvh --replacepkgs centos-release-7-3.1611.el7.centos.2.5.x86_64.rpm
As next you can try to install something with yum and you might get:
[root#dcos-master3 ikerlan]# sudo yum install wget
error: db5 error(-30969) from dbenv->open: BDB0091 DB_VERSION_MISMATCH: Database environment version mismatch
error: cannot open Packages index using db5 - (-30969)
error: cannot open Packages database in /var/lib/rpm
CRITICAL:yum.main:
Error: rpmdb open failed
Now you can try to reboot the machine or try to use the following command to rebuild the rpm db:
rpm --rebuilddb
I came across the same issue while downloading some packages in centos 7. After days of search, I found the solution:
Go to the yum repo directory.
cd /etc/yum.repos.d.
Make a copy of the CentOS-Base.repo file.
cp CentOS-Base.repo CentOS-Base.repo.old
Edit the CentOS-Base.repo file. Comment mirrorlist and uncomment baseurl.
vi CentOS-Base.repo
[base]
name=CentOS-$releasever - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
Now when you use yum, do the following.
sudo yum --disablerepo=* --enablerepo=base install httpd
Likewise for yum update.
sudo yum --disablerepo=* --enablerepo=base install httpd
It should work now.
I ran into this problem when attempting to install MariaDB on CentOS 7. I was super frustrated and after much searching found the answer at this link.
Here is what fixed this problem for me. Run as root.
# yum --disablerepo "*" --enablerepo epel install [package]
# yum clean all
"epel" can be whatever repo you like, but this one worked for me. Place [package] in the command just as written, not what package you are trying to install.
After you run the above, exit root and run whatever install you were attempting before encountering the error.
I noticed that in the failing url, your $releasever is %24releasever, but it should be 7 or 7.14.xx. Please check your yum config file at /etc/yum/var, or search in every .repo file, to see what is its value. It may be corrupted.
See Red Hat documentation for more information about how to set these variables.
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/html/deployment_guide/sec-using_yum_variables
yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm -y
yum -y install yum-utils
yum-config-manager --enable remi-php74
Then proceed to your installation/updates/etc
Always make sure NAT is active on your centos7. Specially when there is a VMnet2 for host. Because sometimes VMNet2 can be active instead of NAT and because of that you will not be able to connect to the internet through centos7. This is just a one reason for getting that error.
