I have access to my server : Through SSH | through the webadmin | direct access via keyboard / screen | …
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : yes
If yes, please explain:
I’ve tried to install additional python packages on the server:
python -m pip install -U pip
python -m pip install -U matplotlib
pip install numpy
pip install matplotlib
pip install pandas
pip uninstall numpy
maybe even more 
Description of my issue
Dear yunohost community,
after installing some phthon packages and rebooting the list of installed apps in the administation interface dont show up anymore.
updating apps via ssh is also not possible anymore
e.g. yunohost app upgrade nextcloud output:
Traceback (most recent call last):
File "/usr/bin/yunohost", line 77, in <module>
yunohost.cli(

installed_version = version.parse(app_infos.get("version", "0~ynh0"))

return Version(version)
File "/usr/local/lib/python3.9/dist-packages/packaging/version.py", line 197, in __init__
raise InvalidVersion(f"Invalid version: '{version}'")
packaging.version.InvalidVersion: Invalid version: '25.0.2~ynh1'
yunohost app list output: https://paste.yunohost.org/raw/laqibidusa
I found no way to fix it jet, should I just remove all additionally installed packages?
Thanks and have a good one!
