Hey guys,
It is not generating the ocr within the Alfresco platform.

You can tested the command directly in the shell using an exmaple file and see what happens

/opt/alfresco/scripts/ocrmypdf.sh --verbose 1 --force-ocr -l por+eng /***/***src.pdf  /***/***target.pdf

Hi kaynezhang,

It just doesn't generate through the Alfresco platform.

Can you help?
Thank you.

kaynezhang

How did you install alfresco ? did you install it manually or install using docker?

jbrasil

Hi kaynezhang,
I installed using the loftuxab script.
alfinstall.sh

https://github.com/loftuxab/alfresco-ubuntu-install

I have always installed this script.
I never had a problem. First time this type of error occurs.
Anything else that needs to be investigated?
Thanks a lot.
