After Console Update to Version 4, Checkmk Crashes.

[Kev98710]

I think the check_mk check crashes, after my Console did a major release Update from Version 3.x to Version 4.x some Minutes ago.

ValueError (invalid literal for int() with base 10: '')

Update:

I uncommented the lines from 123 in the file "/omd/sites/xxx/local/lib/python3/cmk/base/plugins/agent_based/unifi_controller.py", regarding the "unifi update available check". This disables the check for available Unifi updates and resolves the problem quick and dirty, as I am unable to understand the error message to its full extent.
