Don't feel dumb, it is all written and spread out in super complicated
ways but once running, it's alright-ish.
Normal Miniforge3 should be fine unless you know you want pypy.
Unless you know differently, try the "Miniforge3-Linux-x86_64" version.
Mamba is something hidden in the background, for you it will pretend to
be Conda. Conda is the original project, mamba is a faster, compatible
alternative.
Miniforge is something that comes with mamba "as conda" and
automatically uses the big "conda-forge" repository where lots of
software and libraries are available, packaged by the community.
You can use the command lines from
https://github.com/conda-forge/miniforge?tab=readme-ov-file#install
After installation I recommend: $ conda config --set auto_activate_base
false
Otherwise every terminal/shell session will run using a conda
environment instead of your standard system environment.
Once installed, you can use the "create" line from other previous mail
to install a QGIS environment. Then "conda activate qgis_3.34" to
activate it in a terminal session, "qgis" in that same terminal to
launch that QGIS and just close the terminal or enter "conda deactivate"
to deactivate it again.

Hi Hannes,
Thanks for you answer. I played around before with those snakes and
that's what maybe brought me into trouble.
And again, this zoo of species starts to confuse me, starting with the
installer:
Miniforge3 or Miniforge-pypy3 ?
And when does the mamba come into play instead of the conda?
Sorry for me playing the dumb, but I almost spent a week trying to get
things back to normal here at my desk.
Cheers,
Bernd

Hi Bernd,
a pragmatic solution which I have grown to like is using conda
environments. Using mamba instead of the default conda via
https://github.com/conda-forge/miniforge to reduce annoyances and
then it is for example a simple "conda --create qgis_3.34 qgis=3.34"
to get a nicely isolated QGIS 3.34 with pdal etc.
Just make sure to deactivate the base environment in your
terminal/shell, otherwise you are trading one potential mess for
another ;)
Cheers, Hannes

Hi,
using QGIS on the "normal" ubuntu-based Linux Mint for years, I
again managed to render my system unusable by playing around too
much, resulting in ever crashing QGIS so I even had to reactivate a
Windows Virtual Box to be able to work!!
After a hell of problems with NVIDIA graphics drivers (opencl
support in QGIS), I finally managed to get everything to work with
Linux Mint Debian edition ... but now had to learn that Debian does
not provide PDAL for point cloud stuff in the repositories.
Long story short: Can anyone give me recommendations how to get PDAL
working with QGIS that do NOT include building PDAL and QGIS by myself?
Though I USE Linux for over 15 years,I would prefer avoiding that.
Fumbling around with too less insight on what I am actually doing
just led me here...
Cheers,
Bernd
