Error updating 8/24/2020 package libffi8ubuntu1 (possibly renamed from libffi8.1.0)

[Cody Ferber]

Hello just updated like I do most days on 20.10 and I got this dependency issue. It looks like this package was just recently renamed within the last few days maybe?

This package is only available in groovy-proposed, which is not intended to be used by end users. Please remove groovy-proposed from your sources.list.

The issues described are normal transient installability issues in proposed, and not a bug.

[Cody Ferber (codyf86)]

Fair enough, but it literally says right above the check box.

Use proposed updates if you're willing to report bugs on any problems that occur.

So something is wrong at least in terms of when you do move it into the main repo.

But you also might want to remove that text if you don't want people to use it and report bugs. :x
