Hi,

I just installed Siril 1.4.0-beta1, playing with the astrometry and photometric calibration. The remote server was not available for a moment so I tried looking for having the data locally. But the Python script fails:

20:22:53: Starting script /home/user/.var/app/org.siril.Siril/data/siril-scripts/core/Siril_Catalog_Installer.py
20:22:54: Error initializing application: no display name and no $DISPLAY environment variable
20:22:54: Python process (PID: 1581) exited with status 1

If I show the content of $DISPLAY on a terminal, it does have a content (:0), so I don’t get why Siril does not see it.

We need more information.
How did you get the package?
Did you compile it yourself? etc.

I have the same issue with python scripts in Linux, saying no display name and no $DISPLAY environment.

I’ve tried the Siril catalogue installer script, the Cosmic Clarity denoise and Cosmic Clarity sharpen scripts, all with the same error code.

I got all the scripts from the Siril “get scripts” section by ticking the box next to the scripts.

Any ideas?

well… same questions.

Siril installed from flathub, scripts downloaded from within Siril. Nothing compiled myself. Ubuntu 24.04. What else do you need?

I managed to solve the problem. The script does not appear to work with Wayland; I rebooted and selected Xorg as the windowing system and the script worked without issues. If I switch back to Wayland, I get the original error again.

Don’t use flatpak on ubuntu, use apt: Installation on GNU/Linux — Siril 1.4.0-beta1 documentation
