Fedora 20 yum update problem with repomd.xml -- Error 404 - Not Found

Hi, I've been using Fedora 20 for a while, but I'm still a newb. I'm trying to install emacs via yum, and I'm having some difficulties. In particular, if I do the following

$sudo clean all  I get Loaded plugins: langpacks, refresh-packagekit Cleaning repos: Dropbox adobe-linux-x86_64 fedora fedora-debuginfo fedy : google-chrome home_DarkPlayer_Pipelight oncloud rpmfusion-free : rpmfusion-free-updates rpmfusion-nonfree : rpmfusion-nonfree-updates updates Cleaning up everything  and then the problem: $ sudo yum update


yields

Loaded plugins: langpacks, refresh-packagekit
Dropbox                                                                                                                                                    |  951 B  00:00:00
Trying other mirror.

One of the configured repositories failed (Fedora 20 - x86_64),
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 fedora

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=fedora.skip_if_unavailable=true

failure: repodata/repomd.xml from fedora: [Errno 256] No more mirrors to try.


I've tried

$wget http://download.fedoraproject.org/pub/fedora/linux/releases/20/Everything/x86_64/os/repodata/repomd.xml  which yields --2016-02-15 07:02:41-- http://download.fedoraproject.org/pub/fedora/linux/releases/20/Everything/x86_64/os/repodata/repomd.xml Resolving download.fedoraproject.org (download.fedoraproject.org)... 140.211.169.196, 140.211.169.206, 67.219.144.68, ...

Anyway, I'm at a loss for what to do next, so any help would be appreciated. edit retag close merge delete Comments probnably not what you want to hear, but I think it is going to be faster and more reliable to just do a fresh install of fedora 23 as there are a number of significant changes since Fedora 20 ( 2016-02-15 08:56:04 -0600 )edit That would be rather unfortunate. I'm running this on a MacBook Air which I had the IT people at a previous employer set up for me (not in a virtual box, and not dual boot). I'm not confident in my ability to do a fresh install on this machine. ( 2016-02-15 09:17:20 -0600 )edit Those repos are offline because Fedora 20 is end of life since mid 2015. I would do a fresh reinstall of Fedora 23 (after backing up) as suggested by @bodhi.zazen. If you still want to try to uprade, take a look a this wiki article about FedUp. sudo yum install fedup sudo fedup --network 23 --product=workstation  ...should do the trick. You may need to download an rpm for fedup (whatever version was included in Fedora20) if Fedora repo is not available.

#metalink=https://mirrors.fedoraproject.org/metalink?repo=updates-released-f$releasever&arch=$basearch


But, as everybody agrees, the best thing to do is to go for the latest version of Fedora.
