Bitte die Ausgabe von

nach ablage rein.

ls -al /etc/apt/trusted.gpg.d/

sowie

cat /var/log/apt/term.log

wenn die Ausgabe auch recht lang ist bitte auch in die Ablage .

Laß mich raten

apt-key list

crasht auch.

So ist es:

apt-key list
Segmentation fault (core dumped)

Ich sehe sehr schwarz.

sudo ldconfig

der Trigger für libc-bin wurde nicht abgearbeitet. Es scheint so, das rklm's Befürchtungen zutreffen und Du Dir evtl. beim compilieren Bibliotheken überschrieben hast.

erstell Dir eine Paketliste

Deine eigenen Einstellungen bleiben bei eine Neuinstallation erhalten, da Du $HOME auf einer eigenen Partition hast.

2 mal hat der Befehl

touch

nicht funktioniert.

ldd /usr/bin/touch

Also sind die coreutils betroffen. Ich denke nicht das so Verzweiflungtaten wie die Maintamer-Skripte zu löschen oder die Status-Datei von dpkg zu manipulieren hilft. Früher oder später klatscht Dir das wieder vor die Füße.

Sorry Taomon

Na dann hilft leider eh nur die letzte Variante was...Vielen Dank jedenfalls für die Bemühungen!...Das Problem ist mir eigentlich auch noch nie untergekommen in den letzten 10 Jahren 😉
