http://repos.fedorapeople.org/repos/...ta/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: epel-erlang. Please verify its path and try again
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest


major point it is --> http://repos.fedorapeople.org/repos/...ta/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"

this started after I had install epel-erlang but not by this url - http://repos.fedorapeople.org/repos/...ata/repomd.xml because it isn't working...
how am I remove this url from repo or any another action which help me?

If you look at: http://repos.fedorapeople.org/repos/peter/erlang/
They only have directories for epel-5, where your machine is looking for epel-6, which doesn't exist on that repo.


You can disable it like so;
Open /etc/yum.repos.d/epel-erlang.repo and change to 0...
Or just delete the repo file,

yes, it works... many Thanks! really appreciate it)
