Hi Zhang Xun, the reason was that my scripting missed some renaming, and therefore the exception for createrepo, which must run with `--compatibility` for centos 7, was not hit. After re-running `createrepo` and reuploading, it looks fixed on my side. Please note that CentOS 7 may get discontinued without notice when we find out that our tooling breaks beyond repair. Iŧ's hard to keep the build machinery running for a discontinued distro. Thank you for your report! Maria On Sat, Jun 13, 2026 at 10:33:43PM +0800, zx--- via Bird-users wrote:

Hi there,

Some of my servers are still using CentOS 7 and I'm following https://bird.nic.cz/get-bird/ to install bird, but it looks like CentOS 7 repo is broken?

[root@localhost ~]# yum-config-manager --add-repo https://pkg.labs.nic.cz/rpm/bird/centos/7/x86_64/bird.repo Loaded plugins: elrepo, fastestmirror adding repo from: https://pkg.labs.nic.cz/rpm/bird/centos/7/x86_64/bird.repo grabbing file https://pkg.labs.nic.cz/rpm/bird/centos/7/x86_64/bird.repo to /etc/yum.repos.d/bird.repo repo saved to /etc/yum.repos.d/bird.repo [root@localhost ~]# yum update Loaded plugins: elrepo, fastestmirror Determining fastest mirrors base | 3.6 kB 00:00:00 bird | 1.5 kB 00:00:00 epel | 4.3 kB 00:00:00 extras | 2.9 kB 00:00:00 updates | 2.9 kB 00:00:00 bird/primary | 11 kB 00:00:02

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. Run the command with the repository temporarily disabled yum --disablerepo=<repoid> ...

4. Disable the repository permanently, 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> or subscription-manager repos --disable=<repoid>

5. 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
