Server permission issues: readonly/500

Jest · 09-11-2022, 11:14 PM

I have successfully installed Calibre in a Docker container on my NAS, and can access the application and content server. However, there is a permissions issue somewhere along the line:

calibre server listening on 0.0.0.0:8081
OPDS feeds advertised via BonJour at: 172.17.0.2 port: 8081
Unhandled exception in state: State: _job_done Client: 172.17.0.1:51740 Request: POST /book-set-last-read-position/library/661/EPUB HTTP/1.1
Traceback (most recent call last):

File "calibre/db/backend.py", line 1019, in execute
apsw.ReadOnlyError: ReadOnlyError: attempt to write a readonly database

I also receive an Ajax/500 error in the browser when reading.

PUID and GUID match the owner of the files, though the Guacamole Client user is named "abc" with the correct UID.

I'm very close to the synced highlights/reading position we're all hoping for—any help would be greatly appreciated.

Fix whatever is breaking the permissions on metadata.db. Or dont use docker. Use the calibre binaries directly. There is no need for the added complication.

Things are working well now with Docker, though I didn't do anything noteworthy with permissions. I'll keep an eye on it. Via the browser I'm able to read/highlight/make notes on any device, regardless of operating system or network.

Thank you for the tremendous product. It has quietly just worked for me for over a decade.
