dist-upgrade did not work

[Christian Treczoks]

I tried a release upgrade, and it didn't work. I disabled the PPAs as requested (minetest, inkscape, libreoffice, and yt-dlp), but it still didn't work. I tried to make sense of the log, but removing fontconfig-config seemed to be more of a problem than a solution, so I reported this as requested in the error message.
