Despite efforst the Nextcloud Desktop version in Discover and dnf5 are still stale, broken versions. Yes I know there are AppImage and Flatpak versions. The version has a e2ee version that is incompatible with other version and seriously breaks users files making the inaccessible.
It is beyond my comprehension why this is not addressed. And why there are no means to discuss this with Fedora package managemen.
What would the means be to have this package removed?
From the report which you link, simply updating the client is not a full solution. It might be a prerequisite, but even that is not clear.
You mentioned “efforts” but did not link to them. So you may or may not have undertaken some of these steps:
submit a bug report on bugzilla describing the bug clearly
verified that an updated client would solve the problem
In case you didn’t get a response for an extended period of time: started the non-responsive maintainer process
