Hi stephh,
I might have run into the same problem like you.
The problem for me was that seafile was installed under /usr/lib/python3.10/site-packages because I used pacaur under Arch Linux to install seafile (which I think could be equivalent in the result to installing with apt-get install).
On the other hand I use anaconda so that this location is not part of my pythonpath.
So one way of fixing the issue was
export PYTHONPATH=/usr/lib/python3.10/site-packages
Of course you have to set this path accordingly to your installation. This can be seen more as a hotfix cause it damages the barrier which is anaconda trying to set up. Right now I am trying to install the seafile package to my anaconda installation.
