Ich habe jetzt spaßeshalber mal nvidia-driver-450 entfernt und dann wieder neu installiert. Vorher hatte ich alle i386-Pakete entfernt. Jetzt sieht es so aus:

Die gehen auch mit 'apt autoremove' nicht wieder weg, wahrscheinlich weil sie von gcc-10-base:i386 benötigt werden. Den hat mir aber auch der Nvidia-Treiber eingebrockt.
Erst mit einem 'aptitude purge gcc-10-base:i386' und dann noch 'aptitude purge libc6:i386 libgl1-mesa-dri:i386' bekomme ich sie wieder weg.
