Plugins don't work after reinstallation

[octaviospain]

For some reason my beets installation gave me errors, so I removed it and installed it again. Wrong move.
Now, I get this output when running beets --version, either by installing it via pip or apt repository.

→ beet --version

First of all, you're affected by this: #3674 which might have been your initial problem. Regarding actual plugin issues, you seem to be lacking some of the plugins' dependencies (discogs_client and so on), they need to be installed manually. The errors with beets.check and wlg (not sure about that the latter, I don't know this plugin, and I've not seen an error like this before) rather look like something is up with your installation. Maybe try removing wlg and the pluginpath configuration, I would guess that the issue is most likely with this manually installed plugin. See also #3752, #3752

FWIW, check and wlg (i.e., whatlastgenre) are both third-party plugins that need to be installed separately.

Thanks for the quick answer. I've reinstalled python2, python3, and pip3, and removed wlg and beets-check plugins that caused trouble. Now I get this error message

Please follow the link that I mentioned above: #3674. This is a known issue on recent versions of Python, unfortunately a fixed version of beets is not yet released.

At the end, when I reinstalled, my Ubuntu machine was broken and never managed to log in again. Probably I accidentaly removed python system packages when trying to solve this, so when I reinstall the system I will have a fresh install, I hope I won't experience this problem or others then. Thanks anyway.
