Incorrectly named Backups result in pip warnings

[furgo16]

I upgraded ifcopenshell via the Addon Manager's Python Dependency Manager. That worked great. However, it seems some sort of backups of the old versions are left over (notice the missing i in the package name):

• ~fcopenshell-0.8.1
• ~fcopenshell-0.8.1.post1.dist-info

Those backups create multiple pip warnings:

WARNING: Ignoring invalid distribution -fcopenshell (/home/me/snap/freecad/common/.local/lib/python3.10/site-packages)

Are these backups intended to be there? What's their use case? Roll back to a previous version?

I notice there is a similar mechanism for workbenches, although the name does seem to be correct there (see fcVM.backup1749448662.6572056 (Disabled) in my About info, it's a workbench I just uninstalled)

That's very strange -- the pip-installed stuff isn't really controlled by the Addon Manager directly, so pip itself seems to be leaving something behind. The Workbench backups are indeed manually made by the AM. I've been meaning to write code to clean them up after a while, but it's never quite made it to the top of the priority list.

I've added the code to cleanup the workbench backups now -- I don't have any idea what's going on with the backups that are interfering with the pip install, those aren't the addon manager. I'm going to close this as not actionable, but if anyone has further information about what might cause those backups and how we can prevent them, please re-open.
