No module named '_gdal'

[ACalleros]

What is the bug or the crash?

I am running Arch linux and updated qgis to the latest release. Since, it hasn't been able to locate gdal. It's the first time I have this kind of problem, what can I do?

`Couldn't load plugin 'processing'

Also tried using a flatpak with the same error

`Couldn't load plugin 'processing'

Out of curiosity, have you enabled the Processing plugin (in Plugins Manager)?

Yup, gives me the same error

It looks like a packaging issue for Arch Linux / EndevourOS: please see https://gitlab.archlinux.org/archlinux/packaging/packages/qgis/-/issues/1

I had this issue in my Manjaro install. The steps to fix it in my case was installing the arrow package and its dependencies. See OSGeo/gdal#6281.

To verify it is fixed, try running gdalinfo --version on console:

$ gdalinfo --version
GDAL 3.8.4, released 2024/02/08

If you still see errors on the form ERROR 1: libarrow.so.1500: cannot open shared object file: No such file or directory then I can't help further, but that's your path to fixing the error and finding extra info on the internet (or at least it greatly helped me).

A final note is that QGIS opens fine even if the output from $ gdalinfo --version is ERROR 1: libpodofo.so.2: cannot open shared object file: No such file or directory, but you'll see some features not working. To fix that error, I installed podofo.

I tried installing the missing files, in my case mariadb and libheif, but I am still getting No module named gdal

[dangarciahe]

Sorry, I don't remember having that issue. Try checking gdal in your repos.

As a last resort work-around, you can try installing QGIS using Conda. The dependencies are handled in a different way in Conda, which solved some of the issues I had.
