I had again the issue on a other Xubuntu 22.04.4 computer (a desktop). Here is how I fixed it:
From command line (sudo apt update && upgrade), the same components were again not updated. So I typed this command line: $ sudo apt upgrade python3-update-manager update-manager update-manager-core The 3 files have upgrade from 1:22.04.19 to 1:22.04.20 After that, Gnome-software (v41.5) is OK (no more updates waiting). The problem seems related to a Gnome-software bug ( https://gitlab.gnome.org/GNOME/gnome-software/-/issues/1114 ). ** Bug watch added: gitlab.gnome.org/GNOME/gnome-software/-/issues #1114 https://gitlab.gnome.org/GNOME/gnome-software/-/issues/1114 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2047579 Title: gnome-software unable to install updates ('Prepared update not found') To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/2047579/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
