The conda-libmamba-solver documentation seems out-of-date (now that mamba is the default solver)?

What happened?

I have read the conda-libmamba-solver main User's guide page, and it feels really weird and confusing, now that libmamba is the default solver in recent installations

For instance, I have an up-to-date version of conda (and related packages): 24.7

> conda list conda
# packages in environment at /home/share/unix_files/cdat/miniconda3_2024-03:
#
# Name                    Version                   Build  Channel
conda                     24.7.1          py312h7900ff3_0    conda-forge
conda-content-trust       0.2.0              pyhd8ed1ab_0    conda-forge
conda-libmamba-solver     24.7.0             pyhd8ed1ab_0    conda-forge
conda-package-handling    2.3.0              pyh7900ff3_0    conda-forge
conda-package-streaming   0.10.0             pyhd8ed1ab_0    conda-forge
conda-which               0.2.0              pyhd8ed1ab_0    conda-forge

And limamba is the default solver since conda 23.9

Yet the user's guide seems to be written for people who still use old versions (e.g. Update from the experimental versions (22.9 and below))

And the tip at the bottom of the page (If you are unsure what configuration is being used by conda, you can inspect it with conda config --show-sources) make no sense for users having a recent version. In my case, I get

 > conda config --show-sources
==> /home/users/jypeter/.condarc <==
channel_priority: strict
channels:
  - conda-forge
  - defaults

I have to use conda info or conda config --show if I want to get the solver information

> conda info | grep solver
                 solver : libmamba (default)
             user-agent : conda/24.7.1 requests/2.32.3 CPython/3.12.3 Linux/3.10.0-1160.108.1.el7.x86_64 centos/7.9.2009 glibc/2.17 solver/libmamba conda-libmamba-solver/24.7.0 libmambapy/1.5.8

> conda config --show | \grep solver
sat_solver: pycosat
solver: libmamba
solver_ignore_timestamps: False

Maybe the page should have different sections, based on the conda version? Or dealing with older versions should go to the FAQ ?

• if you have conda >= 23.9
• if you have 22.11 (?) <= conda < 23.9
• if you have very old versions of conda (conda <= 22.11 ?) : just install mamba directly and use it as a replacement of conda. I maintain a legacy installation based on conda 4.9.2 where I hase succesfully used mamba for a long time

Thanks, yes, this suggestion is spot on. I'll push a PR shortly.
