Why your system linked to fedora-41 repos?
In QubesOS 4.3 fedora42 is standard out of the box, fedora 41 is QubesOS 4.2.x…

[OvalZero]

Because dom0 is based on Fedora 41. Standard template (in QubesOS 4.3) for app- or service-qubes (!) is Fedora 42 and testing is Fedora 43.

Ahh, sorry i am misreading that.
Forget my unqualified reply.

See :

Dom0 update error, fresh Qubes 4.3 install

Looks like uploading core-admin-client v4.3.27 (r4.3) · Issue #6369 · QubesOS/updates-status · GitHub to the stable repository was premature… This needs matching core-admin v4.3.41 (r4.3) · Issue #6370 · QubesOS/updates-status · GitHub, but this one has still some issues, so it isn’t suitable for stable upload. The update issue should be fixed in few hours (after buggy package is removed from the stable repo).
