Yesterday I installed Anki from the repos and it worked fine (apart from the theme annoyances described in this post https://discuss.getsol.us/d/3658-anki-is-unreadable-with-plata-noir-on-budgie). Today I checked for missing pip dependencies with
pip3 check and I got:
anki 2.1.35 requires distro, which is not installed.
anki 2.1.35 requires orjson, which is not installed.
So I just installed them myself.
I don't know if this is an issue or not, or if it's already known.
