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/

Fatal error: gtkplugin.h: no such file or directory
I am trying to use make to install plugin for pidgin on centos 8 we have seen the above error.
Even after installing gtk,gtk2/3 devel packages we couldn't get the headfile.
The problem is with centos 8 distribution since there is no pidgin-devel package by default yum installation. So with the use of dnf command and enabling powertools we can install it by using the below command:
dnf --enablerepo=powertools install pidgin-devel
Please refer the link
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
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.
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

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.
Can anyone tell me how to configure a CentOS/Fedora yum repo to install vncserver on RedHat 6.3
Now install few required packages for vnc-server:
# yum install pixman pixman-devel libXfont
After installing required packages, lets install vnc-server in your system. vnc-server is available under default yum repositories.
# yum install vnc-server
On CentOS/RHEL 6, you will see that tigervnc-server package will be installed.
Create user1 and set password and Now set the vnc password for all accounts need to connect through vnc.
su - user1
vncpasswd
Now edit /etc/sysconfig/vncservers configuration file and add the following to the end of the file.
VNCSERVERS="1:user1"
VNCSERVERARGS[1]="-geometry 800x600"
VNCSERVERARGS[2]="-geometry 1024x768"
Where VNCSERVERS is the list of users need to connect, VNCSERVERARGS defined the screen size. Like user1 have a 800×600 screen, and user2 have 1024×768 screen size on his client.
Now start vnc-server service using following command and check the output
service vncserver start
To access from remote Linux system use following command.
# vncviewer 192.168.1.11:1
All you need to do is run the following command
yum install tigervnc -y
When you are installing tigervnc, vnc-server will install along with it.
yum whatprovides vnc-server
tigervnc-server-1.1.0-5.el6.x86_64 : A TigerVNC server
Repo : base
Matched from:
Other : vnc-server
Base repo is inbuilt for redhat. Please let me know if that helped you. :)
