Resolving EPEL 404 errors (yum errno 14)
Today, I ran into an interesting issue with yum where I was unable to contact EPEL repository mirrors – every mirror was throwing “filelists.sqlite.xz: [Errno 14] HTTP Error 404 – Not Found”. I tried uninstalling and reinstalling the epel-release package, but that didn’t help. It turns out that this issue is caused by cached data in yum and can sometimes happen when repos update.
