I am using Fedora 20 and trying to install several software packages. e.g.
sudo yum install python-matplotlib
And get this response for every package I try:
Loaded plugins: langpacks, refresh-packagekit adobe-linux-i386 | 951 B 00:00 epel/i386/metalink | 38 kB 00:00 Could not parse metalink https://mirrors.fedoraproject.org/metalink repo=epel-7&arch=i386 error was No repomd file One of the configured repositories failed (Unknown), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Disable the repository, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable <repoid> 4. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true File /var/cache/yum/i386/20/epel/metalink.xml does not exist
I don't understand the suggestions enough to confidently attempt them.
I have searched the Internet for a solution and have tried this ...
sudo yum clean all sudo yum update -y
... which had no effect on the problem.
and this ...
[Harry@localhost]~% cat /etc/fedora-release Fedora release 20 (Heisenbug) [Harry@localhost]~% sudo yum distro-sync --releasever=20
... which gave the same "no repomd file" error
Please can anyone help me to resolve this problem?
