Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 stellarium : Depends: qt6-base-abi (= 6.2.4)
E: Unable to correct problems, you have held broken packages.

What to do ?

Thanks

Well, due to problem in ABI dependence (Hello support ZIP) you can:

• Using AppImage or flatpack
• Build Stellarium from source code
• Create a fake package to resolve qt6-base-abi issue

[alex-w]

This doing package builder, not a human…

Thanks @alex-w, I'll use Flatpak for automated updates 👍

I would have tried it earlier, but it's not advertised anywhere, so I didn't know it existed 😅

Therefore I'd like to suggest linking to it on the README and on the website, and adding the flatpakref to releases.

Thanks !

but to reduce the number of dependencies currently we’re using Qt’s code for same tasks and this code is located in qt6-base-private-dev package

Now that we use CPM, can this approach be reconsidered? It's unclean to depend on internals of a library, especially for such a simple reason as reduction of dependencies.

The “problem” was introduced when CPM support was added (see #1295) - qtcompress library using in Stellarium and in QXlsx (dependency)

[alex-w]

Ouch… no official qtcompres library in linux now :(

OK, I’ll try to restore it as “inner” dependency
