Can't connect to system DBus: Error calling StartServiceByName for org.freedesktop.problems: GDBus.Error:org.freedesktop.DBus.Error.TimedOut: Failed to activate service 'org.freedesktop.problems': timed out
…and
'abrt-cli status' timed out
I was not able to find a solution by running restart commands. I believe the problem is related to kernel versions in memory and its dependencies. For the record, the servers i am seeing with this error are in Microsoft Azure.
