Looking at mainlog, update-manager is marked for removal.
Looking at AptLog Broken update-manager:amd64 Depends on update-notifier:amd64 < 3.192.54.8 | 3.192.68build3 @ii umR > Considering update-notifier:amd64 6 as a solution to update-manager:amd64 6 MarkKeep update-manager:amd64 < 1:22.04.20 -> 1:24.04.6 @ii umU Ib > FU=0 Removing update-manager:amd64 rather than change update-notifier:amd64 MarkDelete update-manager:amd64 < 1:22.04.20 | 1:24.04.6 @ii umH Ib > FU=0 We are removing update-manager rather than install update-notifier.
