** Description changed:
+ 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.
