[Bug 2015286] [NEW] update-manager unusable due to TimeoutError in uaclient

Public bug reported:
On a fairly standard installation of lunar (ie no Ubuntu Pro linked
etc), the update-manager can become a non-functional window when
uaclient isn't behaving. This manifests itself in a greyed-out 'checking
for updates' window which doesn't respond to any clicks and can only be
closed by ending the process in the system-monitor.

TimeoutError: The read operation timed out
In my opinion any misbehaving of the Ubuntu Pro integration in update-
manager (in this specific case probably a 'temporary' server issue)
shouldn't cause update-manager to become dysfunctional, especially to
those not subscribed to Ubuntu Pro.
I have recently seen:
- update-manager unable to install updates for over a month ( LP: #2008280 )
- this issue,
- if you turn wi-fi off and open update-manager, then after clicking ok the update-manager window becomes unresponsive ( LP: #2015113 )
- and undoubtedly there are others to come as this is all without uaclient needing to do anything (ie I have no subscription and lunar is not yet released)
Please consider how you might make the integration of Ubuntu Pro into
update-manager more robust, so that any issues in uaclient don't stop
update-manager from functioning correctly. (ie presumably using a
try/except around the uaclient call is not unreasonable - you might
loose track of any errors that are occurring, but keeping update-manager
working (aka allowing people to install their system updates) is a much
higher priority)
Thanks
