Two unreportable bugs on Zesty

I think I have a knack to break things in weird and unexpected ways.

And finally for the win:

[Edit] that localized French error message says "This package is not officially supported by Ubuntu. Please remove any third party package and try again"

Now, I think this happened because I encountered the crashes, could not upload them immediately due to network unavailability, then updated, rebooted and attempted to submit them after that.

Can anyone concur?

Last night (my time) I could not update (404) and now I can, but no such trouble like you.
