Due to the move to repo snapshots (see: https://nobaraproject.org/2023/03/21/march-21-2023/), drpms and zchunks are not supported by the new repos. You may encounter an issue such as:

– Curl error (23): Failed writing received data to disk/application for https://nobara-fedora-updates.nobaraproject.org/37/repodata/21c3520cb9fd62b39b7e4fe786e952d600d66a8051648d2ce4072169bcfcdf60-updateinfo.xml.zck [Failure writing output to destination]

and/or

[MIRROR] curl-7.85.0-7.fc37_7.85.0-8.fc37.x86_64.drpm: Status code: 404 for https://nobara-fedora-updates.nobaraproject.org/37/drpms/……

This has been resolved in later package updates, however it may require initial manual modification first.

Open /etc/dnf/dnf.conf and add this line:

zchunk=False

After that, update the fedora-repos and dnf packages:

sudo dnf update fedora-repos dnf --refresh

This should resolve both issues.
