[Bug 2109758] Re: software updater says there are more updates but wont do them

[J Sharp]

OK - fixed by commenting out lines in /etc/apt/preferences.d/lib.pref

$ sudo apt-cache policy update-manager
update-manager:
  Installed: 1:24.04.13i3

I ran update-manager(old) to check defaukt state and this installed some new updated including new update-manager
running that I get: 
Traceback (most recent call last):
  File "/usr/bin/update-manager", line 39, in <module>
    from UpdateManager.UpdateManager import UpdateManager
  File "/usr/lib/python3/dist-packages/UpdateManager/UpdateManager.py", line 67, in <module>
    from .UpdatesAvailable import UpdatesAvailable
  File "/usr/lib/python3/dist-packages/UpdateManager/UpdatesAvailable.py", line 61, in <module>
    from .Core.UpdateList import UpdateSystemGroup
  File "/usr/lib/python3/dist-packages/UpdateManager/Core/UpdateList.py", line 599
    if pkg.is_installed and pkg.is_upgradable and pkg.marked_keep
                                                                 ^
SyntaxError: expected ':'

So I fixed that by joining 600 to 599 and ran it again.
This time it satarted, did a small update and finished with correct 'The software on this computer is up to date'

Title:
  software updater says there are more updates but wont do them

Status in python-apt package in Ubuntu:
  New
Status in update-manager package in Ubuntu:
  Triaged

Bug description:
  Software updater starts automatically when it detects a new set of updates. When this is done it shows new 
  'Other updates'- 42kB with a sublevel 'System components' both with checkboxes, but you cant select the checkboxes.
  BTW at the bottom of the window it says 16.6 MB will be downloaded (not 42Kb).

  You have to cancel to close the window. At the next update period a
  similar thing happens
