YUM - Repository base is listed more than once
While checking what packages were available using the yum tool I kept getting the message: Repository base is listed more than once in the configuration Repository addons is listed more than once in the configuration Repository extras is listed more than once in the configuration Repository updates is listed more than once in the configuration I couldn't find a great deal of help on the internet (hence this post!) but eventually it turned out that I had a .repo file which was listing the same repositories as my yum.conf file. The .repo file was in /etc/yum_repo.d/ directory, but yours might be called something else. So, check for a /etc/yum* directory and see if you find any .repo files. In my case they were identical so I used renamed the .repo file to .repo.hide and used yum.conf instead. I hope this helps someone as I know I could have done with finding it 2 hours ago! PS. Merry late Christmas.
