Cockpit won't start on Leap 15.6: Trigger limit hit

I’m sorry but I followed all the advices given to make Cockpit (that I installed from Discover) run in my browser on localhost:9090. The browser Firefox cannot make contact with the server on localhost:9090/ Yes, I changed the passwd, group and shadow in etc/nsswitch.conf … but still the result is the same.

What is this “trigger limit hit”?
Thanks for any answer that could help me (I’m afraid what this will mean for Leap 16.0 …)

I had problems with entries in the /etc/nsswitch.conf, you need:

passwd:         compat systemd
group:          compat [SUCCESS=merge] systemd
shadow:         compat systemd
# Allow initgroups to default to the setting for group.
# initgroups:   compat

hosts:          files mdns_minimal [NOTFOUND=return] dns

But cockpit in Leap 15.6 has not all plugins as in Leap 16.0, so no need to install cocpit.

Also Yast is available…

It means that the service triggered by the socket unit failed to start too often.

Not on Leap 15.6, no.
