Bonsoir,
Visiblement il y a le processus 21812 qui n’a pas rendu la main lors des mises à jour :
2025-03-16 19:11:15,782: WARNING - E: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 21812 (dpkg)
2025-03-16 19:11:15,792: WARNING - E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?
2025-03-16 19:11:15,793: WARNING - E: Couldn’t rebuild package cache
2025-03-16 19:11:16,794: ERROR - Migration 0027_migrate_to_bookworm did not complete, aborting. Error: Failed to run command ‘aptitude update’
Il faudrait réessayer de lancer la migration.
Cependant, peut-être faudra-t-il préalablement lancer ces commandes :
sudo dpkg --configure -a
sudo aptitude update
