Linux – EPEL Repo for CentOS 6 causing error

centos6epellinuxyum

I've got a VM running CentOS 6 (64bit) and I'm attempting to add the EPEL repo like usual to install various packages as I do quite regularly.

Today, I'm experiencing some strange errors yet I'm doing absolutely nothing differently.

I'm adding EPEL like so:

# wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
# rpm -ivh epel-release-6-8.noarch.rpm

Yet when I try running yum for anything, I'm getting this error:

[root@core /]# yum list

Loaded plugins: fastestmirror

Determining fastest mirrors

Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

Any ideas? I'm stumped!

The correct fix is to update your SSL certificates.

sudo yum upgrade ca-certificates --disablerepo=epel

You need to disable the epel repo so that this command will succeed. After you update your certificates you can use yum normally as EPEL will work again.

Linux – How to make Yum work on virtual centos 6 on ESXi behind proxy

Check your log files on your proxy server, and the local messages file on the system you are installing on. It is likely you are seeing some other networking error. Does a simple web request like curl work with the given proxy? Can you use curl to pull the mirror list? Also does your proxy require authentication? Also another thing to point out, sometimes the mirror list file points to ftp sites, thus you will need to have FTP allowed through your proxy. It could be your other hosts were never directed to an FTP server so it has not been an issue until now.

Also for the hosts which you say do work through the proxy, are you sure they are actually going through the proxy, and not just bypassing it due to a side effect in yum because there is a direct route to the Internet for them?

You are installing 64-bit package on 32-bit OS. Try this:

rpm -ivh http://apt.sw.be/redhat/el6/en/i386/rpmforge/RPMS/vlc-1.1.13-1.el6.rf.i686.rpm

On my CentOS:

# yum whatprovides *BasicUsageEnvironment
...
live555-devel-0-0.27.2010.04.09.el5.rf.x86_64 : Development files for live555.com streaming libraries
Repo        : rpmforge
Matched from:
Filename    : /usr/include/BasicUsageEnvironment

live555-devel-0-0.27.2012.02.04.el5.rf.x86_64 : Development files for live555.com streaming libraries
Repo        : rpmforge
Matched from:
Filename    : /usr/include/BasicUsageEnvironment

So, install live555 and try again:

# rpm -ivh http://apt.sw.be/redhat/el6/en/i386/rpmforge/RPMS/live555-0-0.27.2012.02.04.el6.rf.i686.rpm http://apt.sw.be/redhat/el6/en/i386/rpmforge/RPMS/live555-devel-0-0.27.2012.02.04.el6.rf.i686.rpm
