I have just installed N7 A3 on my machine, all appeared to install ok. However when I went to install software I got a yum cache error. I started a terminal as root and cleared the cache and ran the install script that I had from Steph. I cannot update and get the error " file contains no section headers file: file:///yum.repos.d/CentOS-Base.repo, line: 1
Any suggestions please.
