Hello! The standard Ubuntu install instructions on the website are wrong. They create a sandboxed executable in your Downloads folder that can’t see other drives, not a true install on the system. Attempting to see other drives will silently fail. the instructions are also not friendly to new Ubuntu users.
Please update the instructions to properly install the software.
Proper install method:
sudo apt update
sudo apt install rawtherapee-data -y
Up to the Rawtherapee people to change their recomendations.

If RawTherapee 5.13 is not yet available in your package manager, you can use the AppImage:
Using kubuntu 24.04 and the RT 5.13 appimage I do not have a problem using an external drive, but that might just be my installation.
You can try adding the --no-sandbox switch as
./RawTherapee_5.13_x86_64_release.AppImage --no-sandbox
Might/might-not make a difference.
Using an apt install for say ubuntu 24.04 will get you RT version 5.10
If you want a regular install and RT 5.13 then enable a PPA as
Hello, on that page I only see the install instructions for Linux for AppImages. They are correct. What’s unfriendly about them?
What did you do to install RawTherapee in your Downloads folder that can’t see other drives? Not the AppImage, isn’t it?
Your “proper install method” will most likely install RawTherapee 5.12 (on Xubuntu 26.04 at least), which is a bit old.
If you want to avoid a ppa to install RawTherapee (as rich2005 suggested), you can get the latest AppImage from here:
That’s strange. AppImages are not sandboxed on their own. Maybe Ubuntu places restrictions on them now.
Anyway, there are no installation instructions specific to Ubuntu (or any Linux distribution). Also, the instructions state this (emphasis mine):
Linux
Software should be installed through your distribution’s package manager.
