What happened?
When I run the conda update --all command, I encounter the following error:
Error while loading conda entry point: conda-libmamba-solver (libarchive.so.19: cannot open shared object file: No such file or directory)
CondaValueError: You have chosen a non-default solver backend (libmamba) but it was not recognized. Choose one of: classic
I've looked into a known issue at conda/conda-libmamba-solver#283 (comment) and tried aligning the versions of libarchive and libmamba using the same channel (either conda-forge or defaults), as well as continuously updating them, but the issue persists.
I've also tried using both flexible and strict channel priorities, but the result remains the same with no resolution.
Additionally, I found a suggestion in google to try conda install -n base libarchive -c main --force-reinstall, but that also didn't change anything either.
I'm currently using Ubuntu 22.04:
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.4 LTS
Release: 22.04
Codename: jammy
Upon checking the anaconda3 directory in my computer, I see that libarchive.so.13 is installed, but I can't seem to install libarchive.so.19 no matter what I try.
Could you suggest any solutions or further actions I might take?
I'm not very familiar with Ubuntu, so if there's any information I've missed or inadequately provided, please let me know, and I'll be happy to provide additional details.
Thank you.
Expected behavior or outcome
Normal operation of libmamba solver

@jylee3247 I think your base environment is messed up already. You should create a separate env for projects and leave the base env untouched.
Try cloning your base env with conda create --name backup --clone base (if you can't do it because of the solving problem, conda env export > environment.yml and reinstall later).
