[Bug 2154139] [NEW] update-manager -c -d did not update from 24.4 to 26.04 LTS

[Ekkehard Ellmann]

Public bug reported:

Ein unlösbares Problem trat während der Berechnung der
Systemaktualisierung auf.

 Wenn keine dieser zutrifft, melden Sie bitte den Fehler mithilfe des
Befehls 'ubuntu-bug ubuntu-release-upgrader-core' in einem Terminal.
Wenn Sie dies selbst untersuchen möchten, finden Sie in den
Protokolldateien unter »/var/log/dist-upgrade« Details zur
Systemaktualisierung. Schauen Sie sich insbesondere »main.log« und
»apt.log« an.
