Multi Language OCR Support

Did the provided suggestion from @neurokrish solve the issue?

[neurokrish]

@nebulon @WiseMetalhead there is some more information here. Looks like there are two options, PAPERLESS_OCR_LANGUAGES and PAPERLESS_OCR_LANGUAGE. The first one determines which packages to install and the second one, which to use. The first option is missing in the paperless.conf file. May be we can add this manually and restart the app?

@neurokrish @nebulon I tried this method earlier, but it didn't work.

My paperless.conf file:

@wisemetalhead according to the docs, the PAPERLESS_OCR_LANGUAGES option should be configured in docker-compose.env and not in paperless.conf. Perhaps @nebulon can help here..

[nebulon]

@neurokrish I have to try this here myself, since the Cloudron app package has nothing to do with their upstream docker image, the default self-hosting config docs would apply instead, so https://paperless-ng.readthedocs.io/en/latest/configuration.html?highlight=languages#ocr-settings

[neurokrish]

@nebulon then may be a standard apt-get install for additional language packs is the way to go?

May be we can install all OCR languages by default using sudo apt-get install tesseract-ocr-all as mentioned here. This way, the app has all languages installed by default and users can choose a specific language by modifying the PAPERLESS_OCR_LANGUAGE flag in paperless.conf.

@neurokrish thanks for the suggestion, at least it solved the issue for me with a deu+eng setting. The just updated package v0.7.0 has those changes.

[neurokrish]

@nebulon great! @WiseMetalhead, can you confirm that the latest update solves your issue with OCR?

[WiseMetalhead]

@neurokrish @nebulon Now it works perfectly! Thanks for the help.

@neurokrish tesseract has a Docker file and it would be nice to support Tesseract on Cloudron.

@LoudLemur tesseract is already installed in the package though.

The thread here (and this forum) is about the Cloudron package of paperless-ngx . It looks like you are using docker installation. You have to take this up with the upstream project. Cloudron also uses docker but it does not use the upstream dockerfiles.
