Applications dont show up anymore in the Adminweb interface

My YunoHost server <3 <3

Hardware: VPS bought online
YunoHost version:

  repo: stable
  version: 11.2.3
  repo: stable
  version: 11.2.1
  repo: stable
  version: 11.2
  repo: stable
  version: 11.2

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 :smile:

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>
  File "/usr/lib/python3/dist-packages/yunohost/", line 41, in cli
    ret = moulinette.cli(

  File "/usr/lib/python3/dist-packages/moulinette/interfaces/", line 503, in run
    ret = self.actionsmap.process(args, timeout=timeout)
  File "/usr/lib/python3/dist-packages/moulinette/", line 580, in process
    return func(**arguments)
  File "/usr/lib/python3/dist-packages/yunohost/", line 597, in app_upgrade
    app_dict = app_info(app_instance_name, full=True)
  File "/usr/lib/python3/dist-packages/yunohost/", line 159, in app_info
    ret["upgradable"] = _app_upgradable({**ret, "from_catalog": from_catalog})
  File "/usr/lib/python3/dist-packages/yunohost/", line 241, in _app_upgradable
    installed_version = version.parse(app_infos.get("version", "0~ynh0"))
  File "/usr/local/lib/python3.9/dist-packages/packaging/", line 52, in parse
    return Version(version)
  File "/usr/local/lib/python3.9/dist-packages/packaging/", line 197, in __init__
    raise InvalidVersion(f"Invalid version: '{version}'")
packaging.version.InvalidVersion: Invalid version: '25.0.2~ynh1'

yunohost app list output:

I found no way to fix it jet, should I just remove all additionally installed packages?
Thanks and have a good one!

Update I’ve uninstalled the packages already but the problem persists

$ pip uninstall matplotlib pandas numpy
