Just updated my calibre-web docker container with the latest version from docker hub on my Synology NAS. The container doesn’t start, in the log there are multiple errors
ModuleNotFoundError: No module named 'flask'
Traceback (most recent call last):
File "/app/calibre-web/cps.py", line 28, in <module>
from cps.main import main
File "/app/calibre-web/cps/__init__.py", line 28, in <module>
from flask import Flask
Is there a bug in the latest build?
More likely to be Synology
Oops, didn’t see that before, assumed since the last dozen or so times I updated the container it worked like a charm, the problem must be the image.
Sorry, you are right, it’s a Synology problem. Deleting old container including image and docker config and then recreating plus redownloading fixed the problem. Less radical measures (duplicating settings, exporting/importing settings) wasn’t enough. No changes in the local folder needed though, so it was still a breeze.
Thanks for the quick response and pointing in the right direction.
