[Bug 1870594] [NEW] Software properties is stuck "Refreshing cache" in an infinite loop whenever I attempt to reload the cache while my PC is disconnected from the internet

[Seija Kijin]

Public bug reported:

When I attempted to change the Software & Updates settings by clicking
on the "prerelease" version, I realized I forgot to connect to the
internet.

I did, but not before clicking the "Reload" button on the desktop.

As a result, even after my PC connected to the internet, now the Cache
Refresh is stuck at 100% completion, instead of finishing, or closing
after giving me an error.
