Currently "guix upgrade fmit" does nothing at all, so I am closing this issue, as there might be a different issue... If you are still interested in the package, it might be interesting to try an upgrade by hand and to also switch to Qt6 if possible.
There are quite a few issues from you on debbugs: https://issues.guix.gnu.org/search?query=submitter%3A%22Dr.%20Arne%20Babenhauserheide%22&package=guix It would be helpful if you could go through them and check if they are still of relevance; if yes it might be a good idea to close them in debbugs and to reopen them on Codeberg.
