So I tried to install epel on a CentOS7 server.
I ran sudo yum install epel-release as per these instructions.
But now whenever I use yum for instance with yum repolist all I get an error:
Repository epel is listed more than once in the configuration
yum advises to disable the repository with : yum-config-manager --disable <repoid>
/etc/yum.repos.d has : epel.repo, epel-testing.repo and localc7.repo if that's of any help
This error usually occurs when you have two repos with the same name. I think you may have named both the epel entries the same.
Try going into /etc/yum.repos.d
Look at both the epel files.
Check the name is different.
cd /etc/yum.repos.d
cat epel.*
Verify that they have different name.
The line you are interested in is:
name=SomeName
If they share the same name just change it so they are different.
Another possibility is that you have the same repo defined in different files. So do:
grep epel /etc/yum.repos.d/*
.. note the duplicates and rename/comment them out.
In my case, the description in [my_reponame] is the same as the other file.
I renamed the description as the filename (or other string).
It works for me.
