Siril 1.4.0 platesolving data won't load.

I am unable to do platesolving as a prerequisite for photometric color calibration, which I am eager to try in Siril 1.4.0.

I get these error messages for both GAIA and NOMAD:

Is there some setting I’m missing?

Or, the welcome document indicates the possibility of downloading this data and using it offline. I have enough disk to do this.

If this isn’t enough, 1.4.0 also introduces a brand-new set of offline catalogs providing extracts from the gold-standard astrometry catalog Gaia DR3. Both an astrometry extract and a spectrophotometric extract are available, and a catalog installer script is provided to enhance the process of catalog installation.

The doc says a script is provided to do this. Where is this script?

servers are down: Plate solving does not work at all since 1.4 beta while prev version has no issues (#1591) · Issues · FA / Siril · GitLab

You should use local catalogues.

Aha! That is the script I was looking for! Thanks.

Well …

16:14:43: Error: python not ready yet. This may happen at first run if the python venv and module setup has not yet completed. Please wait a short time for a completion message in the log and try again.

How long is a short time? Or do I have to configure something on the system?

Okay. It appears that my system (a newly upgraded Ubuntu 24.04.2 LTS system) has python misconfigured:

$ which python
$ which pip
/usr/bin/pip
$ python
Command 'python' not found, did you mean:
  command 'python3' from deb python3
  command 'python' from deb python-is-python3

There is no python command on the system.
python3 is installed on the system.
python-is-python3 was not. I installed that.
Now there was a python command on the system but that did not help matters in siril with this script.

SHEESH!

I’m an old retired python hand and I can’t figure this out! This venv stuff is all new to me. What I read about venv is geared to python developers. I’m not a developer in this situation. I have a feeling there must be a simple way to get this to work, but I don’t know what it is.
