Title: cups broken?
Post by: manilg on 2020/11/30, 10:18:46
Nach dem update auf Version  cups (2.3.3op1-2) funktioniert das Drucken nicht mehr.
localhost:631 ist nicht erreichbar und

Code: [Select]
systemctl restart cups
Job for cups.service failed because a fatal signal was delivered to the control process.
See "systemctl status cups.service" and "journalctl -xe" for details.

Kann ich nicht nachvollziehen. http://localhost:631 geht hier ebenso wie systemctl restart cups.
apt policy cups

Den vermeintlichen cups-Fehler kann ich auch nicht bestätigen, hier ist alles in Ordnung nach dem cups-Update.
Da klemmt irgend etwas anderes in Deiner Installation

Ich kann den Fehler hingegen bestätigen.

Weder cups.service .path oder . socket scheinen zu laufen.

Und auch bei mir führt ein Neustart von CUPS zu
Code: [Select]
# systemctl restart cups.service
Job for cups.service failed because a fatal signal was delivered to the control process.
See "systemctl status cups.service" and "journalctl -xe" for details.

Ein blick in journalctl liefert dann https://paste.debian.net/plain/1174927 (https://paste.debian.net/plain/1174927) wo von einem segfault die Rede ist.

Ich habe bereits cups reinstalliert, leider hat das auch nicht geholfen.

Ich habe das Problem bei mir inzwischen behoben.

Der springende Punkt ist ein simples
Code: [Select]
apt install --reinstall cups
reicht nicht aus.

Was jedoch funktioniert ist ein
Code: [Select]
apt purge cups*
gefolgt von einem autoremove und einem reboot. Dann wieder
Code: [Select]
apt install cups und es läuft.

Ich habe im Rahmen meines Problemlösungsvorgangs auch ein paar Brother-Treiber deinstalliert, bin mir allerdings nicht sicher ob das was damit zu tun hat.
