RawTherapee 5.10 fails to load lensfun database

I installed Ubuntu 24.04 LTS and installed RawTherapee 5.10 (latest stable 2024-07-24) from the Ubuntu App Center. When I run RawTherapee and edit a raw image, the metadata correctly identifies my camera and lens, but under “Profiled Lens Correction”, there are no entries in either the Camera or Lens dropdown menus.

I used apt to install lensfun-update-data and ran it. It installed the xml files in /home/bob/.local/share/lensfun/updates/version_1 and I edited the RT options settings file’s DBDirectory to point to that lensfun DB location. I turned on “Verbose=true” in options and re-ran RT from a terminal. On startup, it says, “Loading lensfun database from ‘/home/bob/.local/share/lensfun/updates/version_1’…FAIL”.

Any suggestions for getting RT to load the lensfun data? I don’t recall having to do any of this under earlier versions of Ubuntu and RawTherapee.

Thanks!

Are you using a snap package perhaps?
