I know rawhide is not supported and all, but curious. Only after removing sdubby or grubby, I can upgrade to rawhide. Before, using --allowerasing or --skip-broken I always get a dependency problem between grubby and sdubby preventing the update from installing. Using freshly updated Fedora 38 KDE in a VM.
reproducible between f39->rawhide sudo dnf system-upgrade download --releasever=rawhide --exclude=sdubby && sudo dnf system-upgrade this command fixed the issue
I can also confirm this issue. Related to 2243872 as this upgrade issue was present between 38 and Rawhide as well.
I'm just going to dupe this as I don't see how this is different than 2243872 *** This bug has been marked as a duplicate of bug 2243872 ***
