Welcome @cantsin

You can find all useful information about Rawtherapee at http://rawpedia.rawtherapee.com

I am not a LINUX user, but what I would do to try to solve the issue:

Localisation and updating of lensfun DB

  • locate the lensfun database. It is a folder with a lot of XML files.
  • update the data base with the lensfun provided script update-lensfun-data as it seems that lensfun packages can be shipped with old or very old data base.
    I think it can happen you have several database in your linux system. Be careful what DB is updated.

Point Rawtherapee to the updated lensfun DB

  • locate the config folder of rawtherapee (don’t know if it is included or no in the appimage). In rawpedia it is said it is located in ~/.config/. I don’t know for appimage. see File Paths - RawPedia

  • In the config folder, you find an option file. Edit the options file and set the DBDirectory key’s value to the absolute path of the custom Lensfun database file.

  • restart Rawtherapee.
