Update notification has bad data and is unresponsive

[Gustavo Niemeyer]

Today I got a pop-up showing a chromium security update pending, but there were two interesting glitches about it:

1) The pop-up was unresponsive. Clicking on Update or Update All did nothing other than visually press and depress the button. See the attached gif animation for details.

2) The data for the chromium update was apparently out of data. Looking at the system data later I could see that the snap was updated to a version which was more recent than the one reported on the dialog. From `snap changes`:

1563 Done today at 12:36 WEST today at 12:36 WEST Auto-refresh snap "chromium"

Thanks for looking into it.

Sorry, the actual version of the snap is missing from that information. Here it is:

$ snap list chromium
Name Version Rev Tracking Publisher Notes
chromium 90.0.4430.85 1564 latest/stable canonical✓ -

Same thing happened today with Telegram Desktop, and this time around the package was indeed pending an update, but buttons still did nothing.

This sounds like the data was out of date, as you state in point 2. Currently we don't have a mechanism for being notified when snapd state changes without polling (https://bugs.launchpad.net/snapd/+bug/1768418). I don't suppose if you remember if you clicked the refresh button in the top left of the window? That would hopefully have gotten updated data.
