Gnubg no longer working after update

[narimiran]

$ gnubg
gnubg: error while loading shared libraries: libpython3.12.so.1.0: cannot open shared object file: No such file or directory

[Mirdarthos]

Please read the announcements before updating:

@philm

Python 3.13 info

You will need to rebuild any AUR Python packages that install files to site-packages or link to libpython3.12.so.

Print a list of of packages that have files in /usr/lib/python3.12/ :

pacman -Qoq /usr/lib/python3.12/

Rebuild them all at once:*

pamac build $(pacman -Qoq /usr/lib/python3.12)

Use rebuild-detector to see if anything else needs to be rebuilt:

 checkrebuild

• It’s recommended to clean your build cache first with pamac clean --build-files

@Mirdarthos

Please read the announcements before updating:

I uninstalled gnubg and then installed it. Shouldn’t that be enough?

But ok, now I did pamac build gnubg, as written in the announcement and… I get the same error.

$ pacman -Qoq /usr/lib/python3.12
error: No package owns /usr/lib/python3.12

[Mirdarthos]

I can’t install it here, so can’t check if it works for me at least. Sorry.

[narimiran]

Now I did. And still no difference.

[Mirdarthos]

I did get it installed just now, and it opened perfectly:

$ gnubg
gnubg

So it would seem to be some kind of AUR package, possibly, that also need to be rebuilt. Have you tried rebuilding them all with:

pamac build $(pacman -Qoq /usr/lib/python3.12)

gnubg depends on another AUR package, gtkglext. I don’t see the connection to Python there, but you may want to try rebuilding gtkglext as well.

[narimiran]

I’ve now run pamac build gtkglext, and after that pamac build gnubg once again, and I still get the same error message as reported above.

[Takakage]

This seems sufficiently complicated that maybe @Mirdarthos or another moderator can split this to its own thread.

I would like to see the actual output from

type -a python
python --version
pamac clean --build-files
pamac build gnubg

Ai ai captn’!

[Takakage]

Did you clean your cache as recommended?

@philm

It’s recommended to clean your build cache first with pamac clean --build-files

Edit: this was originally post #5 in this thread.

You need to update every AUR package

Otherwise some dependencies may be not updated!

[narimiran]

I found a solution.

It seems that something was using my miniconda python (which was at 3.12), and not /usr/bin/python.
I removed miniconda (since I don’t use it anymore), and I’ve re-run the commands proposed above.

Now gnubg successfully runs.

Thank you all for the help!!
