Any attempt to install the nethsecurity-controller app fails norcan I uninstall the corrupted installation.
I have 3 useless instances already.
Attempts to uninstall fails with the following error codes.
This is the one of cluster/remove-module:
Traceback (most recent call last):
File “/var/lib/nethserver/cluster/actions/remove-module/50update”, line 72, in
raise ex
File “/var/lib/nethserver/cluster/actions/remove-module/50update”, line 67, in
raise Exception(f"non-zero exit-code from subtask")
Exception: non-zero exit-code from subtask

And this from cluster/destroy-module:
Assertion failed
File “/home/nethsecurity-controller2/.config/actions/destroy-module/40firewall”, line 11, in
agent.assert_exp(agent.remove_public_service(os.environ[‘MODULE_ID’]))

Both failures have eventually to do with the mentioned 50update file.
I’m not a programmer. What can I do?

I can’t reproduce the issue, here the NethSecurity controller installs without issues and it’s also possible to remove it.

You could try to remove the app on CLI:

Removing the instances on CLI works fine. Thanks for this hint.
But another attempt to install the Nethsecurity-Controller app fails again whereas I could install 7 other apps without any problem.

The error message is now:
Assertion failed
File “/var/lib/nethserver/cluster/actions/add-module/50update”, line 230, in
agent.assert_exp(create_module_result[‘exit_code’] == 0) # Ensure create-module is successful

Create-module? Any idea?

Maybe the disk is full?

No, just 52 % of 40 GB.
