I am having a problem installing the uv4l raspicam on my Raspberry Pi 2. I have done everything multiple times according to the instructions in http://www.linux-projects.org/modules/sections/index.php?op=viewarticle&artid=14 and search the web over and over but no solutions.
For me it seems that the first instruction for saving the key goes ok, although I don't know how to verify it. If I check apt-key list, I don't know what there should be..?
After I have added the line to the sources.list and I try to perform apt-get update, it says:
Failed to fetch http://www.linux-projects.org/listing/uv4l_repo/raspbian/dists/jessie/main/binary-armhf/Packages 404 Not Found
I tried to put both wheezy and jessie ending to the sources.list, and even updated my raspbian version in between, because I couldn't get it working but it didn't help.
Failed to fetch http://www.linux-projects.org/listing/uv4l_repo/raspbian/dists/wheezy/main/binary-armhf/Packages 404 Not Found
And after trying to update it was vain to even try further because the install command fails as well:
E: Unable to locate package uv4l
E: Unable to locate package uv4l-raspicam
Any ideas what I am missing??
Thanks!
The OP seems that simply has a typo problem, but IMO the people that arrives here is trying to solve the Unable to locate package uv4l when they run:
sudo apt-get install uv4l
So I'll try to give a more detailed steps on how to solve this problem.
First install the key for the repository where uv4l is located, to do so run:
wget http://www.linux-projects.org/listing/uv4l_repo/lrkey.asc && sudo apt-key add ./lrkey.asc
Then edit the /etc/apt/sources.list and add this repository at the end of the file:
deb http://www.linux-projects.org/listing/uv4l_repo/raspbian/ wheezy main
Finally update the packages list:
sudo apt-get update
And now you can correctly download the uv4l.
sudo apt-get install uv4l
And how stupid can one be...
Remember to write everything correctly raspbian NOT raspian...

I have installed MongoDB on my Linux meant. I can't figure out the error.
Actually, it is a warning like this
W: http://downloads-distro.mongodb.org/repo/ubuntu-upstart/dists/dist/Release.gpg: Signature by key 492EAFE8CD016A07919F1D2B9ECBEC467F0CEB10 uses weak digest algorithm (SHA1)
Can anyone help me to figure out the problem.
EDIT:
I wrote sudo apt-get update in the terminal. I got this warning in the last line on the each update.
Try sudo apt-get upgrade instead of sudo apt-get update
To see if any package upgrades are available use
sudo apt update (notice it's just apt) does provide feedback about the results.
By using apt, you will either see a message that
All packages are up to date
or
The following packages will be upgraded
Also see apt list --upgradeable.
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.
While am compile using swift build, am getting following error in my Ubuntu machine
$swift build
/home/xxxxxxxxx/Downloads/swift-DEVELOPMENT-SNAPSHOT-2016-02-25-a-ubuntu15.10/us
r/bin/swift-build: error while loading shared libraries: libicuuc.so.55: cannot
open shared object file: No such file or directory
How can i fix this issue?
Thanks.
You can manually download the good .dep
wget http://security.ubuntu.com/ubuntu/pool/main/i/icu/libicu55_55.1-7_amd64.deb
Then you run:
sudo dpkg -i libicu55_55.1-7_amd64.deb
If it miss some dependency:
sudo apt-get -f install
It has worked for me.
Your can find the other architecture on the debian package website :
https://packages.debian.org/sid/libicu55
p.s: I know this is on SID, but this is the only version that I found
*note...packages may have been removed
Your system lacks a critical component for building Swift, libicu-dev.
Install this:
sudo apt-get install libicu-dev
But that was for building Swift from source. You were talking about building with Swift, my apologies.
Unfortunately it seems it won't work either: Swift for Linux only officially runs on Ubuntu 15.10 and 14.04, and you tell me in the comments that you're running 15.04.
I know there's tutorials on the web on how to make it work on Mint and other distros... But the best would be, if possible, that you update your install of course.
I searched on the net and find a list in debian packages that shows the libicuuc.so.55 file.
apt-get install libicu55
Will resolve the issue.
hallow_me's link to download libicu55_55.1-7_amd64.deb doesn't work.
Here are the latest links https://packages.debian.org/stretch/amd64/libicu57/download
Like
wget http://ftp.us.debian.org/debian/pool/main/i/icu/libicu55_55.1-7_amd64.deb
Then follow hallow_me's instruction to install it.
Try the followings lines
echo "deb http://security.ubuntu.com/ubuntu xenial-security main" | sudo tee --append /etc/apt/sources.list
sudo apt-get update
sudo apt-get install libicu55
I'm working on a remote server (Ubuntu 14.04) through SSH -X. I have installed Sublime Text and when I try to open it I get
Gtk-Message: Failed to load module "canberra-gtk-module"
Unable to connect to dbus
How do I solve this?
sudo apt-get install libcanberra-gtk*
if you run that install it will get 120+ mb of libs, mostly. to get rid of that module error, you only need to install 70k. i fixed the same error with this single package:
sudo apt-get install libcanberra-gtk-module
that should do the trick. if that doesnt work try installing only the canberra libs, you don't need all those Xlibs, or you'd have them already ;)
here's just canberra packages apt listed:
libcanberra-gtk-common-dev libcanberra-gtk-dev libcanberra-gtk-module
libcanberra-gtk-module-dbg libcanberra-gtk0 libcanberra-gtk0-dbg
libcanberra-gtk3-0-dbg libcanberra-gtk3-dev libcanberra-gtk3-module-dbg
libcanberra-dev
10 total packages, instead of over 100 packages with that * wildcard. save space, boot time, sys speed etc, always, if you can :)
As I found at the end of this thread, it appears to be a problem with the libcanberra dependencies, I stumbled upon this and the solution worked for me on Sublime Text 2/Debian 8.
So try running this:
sudo apt-get install libcanberra-gtk*
This got rid of the GTK message, but the "Unable to connect to dbus..." stuff disappeared when I executed sublime as a non-root user.
On Debian Stretch:
sudo apt install libcanberra-gtk-module
This will install:
The following additional packages will be installed:
libcanberra-gtk0
The following NEW packages will be installed:
libcanberra-gtk-module libcanberra-gtk0
I currently have a problem with rpmlib(fileDigest) and (PayloadIsXz) I've searched on Google and other websites, including SO without luck (that worked). This is basically what I do:
wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-7.noarch.rpm
rpm -ivh epel-release-6-7.noarch.rpm
And this is what it spits out:
[root#XXX ~]# rpm -ivh epel-release-6-7.noarch.rpm
warning: epel-release-6-7.noarch.rpm: Header V3 RSA/SHA256 signature:
NOKEY, key ID 0608b895 error: Failed dependencies:
rpmlib(FileDigests) <= 4.6.0-1 is needed by epel-release-6-7.noarch
rpmlib(PayloadIsXz) <= 5.2-1 is needed by epel-release-6-7.noarch
I've searched on Google for those two, but it didn't quite help.
Note: uname -m gives "i686" if that's any help.
As well as I run CentOS 6.3
I know it may seem super silly but try:
yum upgrade
and run the installation again
and instead of using rpm, try a yum:
yum localinstall /path/to/your/rpm/epel-release-6-7.noarch.rpm
Yum will try to automatically resolve dependencies, where rpm wont. not 100% sure that will fix it, but definitely something to try :)
