After today’s upgrade from 18.04 to 20.04, I’m no longer able to start seahub with CE 7.1.4. On 18.04 it worked. I made sure to install all python dependencies and packages mentioned in the upgrade guide after the upgrade to 20.04, yet, something seems to be wrong/missing.
To get a log, I used start-fastcgi:
seafile-server-latest/seahub.sh start-fastcgi
LC_ALL is not set in ENV, set to en_US.UTF-8
Starting seahub (fastcgi) at 127.0.0.1:8000 …

import Image
ModuleNotFoundError: No module named ‘Image’
Error:Seahub failed to start.
Using python, I can from PIL import Image
or from PIL import _imaging
without problem, so I’m guessing there is some problem with the bundled PIL.
Does anyone have an idea how to fix this or do I have to go back to 18.04?
Any help is greatly appreciated
