[fedora 36] error downloading http://mirror.in2p3.fr/pub/fedora/linux/releases/36/Everything/x86_64/os/Packages/d/device-mapper-libs-1.02.175-7.fc36.x86_64

[Hervé Beraud]

Hey there,

I initially faced issues with osbuild-composer where all my build failed without infos in logs (osbuild/osbuild-composer#2224).

By digging in journalctl I can see that each time I ran build I faced the following error:

My builds failed because osbuild/host.py tried to pull from a mirror that doesn't exist: http://mirror.in2p3.fr/pub/fedora/linux/releases/36/Everything/x86_64/os/Packages/d/device-mapper-libs-1.02.175-7.fc36.x86_64

Indeed I'm using fedora 36 and this mirror seems to be a bit outdated and the last fedora version available is fedora 34 (http://mirror.in2p3.fr/linux.html).

However, I didn't find trace of how osbuilder determine this url.
Do you know how to fix that and do you know where/how is determined this url?

Thanks in advance

Closing on favor of osbuild/osbuild-composer#2224 since there is nothing that osbuild can do if the URL in manifest is not reachable.
