Bug description:
Impact
------
This bug was is a regression of the bug fix LP:2058133; It held back
the phasing of the package.
The symptom is that update-manager crashes right at start, doesn't
launch.
The ua.updates() and current_news() end-points are documented to throw
no exceptions, but actually they might, in which case this bug is
encountered. As such, the proposed fix tries the API but ignores
exceptions raised by it, causing update-manager to still work, even if
the Pro packages end up being classified as normal packages or if Pro
news aren't displayed.
Test plan
---------
Run 'UA_CONFIG_FILE=/ update-manager --no-update', update-manager
should launch, not crash.
Where problems could occur
--------------------------
If the API end-points are working, ensure that classifying Pro
packages as such and displaying possible Pro news continues to work.
Original report
---------------
Looks like ua.updates() can actually throw an exception. Only that
would explain this crash.
