When I started up Evolution this morning, it presented me with an error like
The name :1.60 was not provided by any .service files
(1.60 may be another number in your case) and wouldn’t let me open my Google mail account. Several attempts to reconnect to the service failed.
Fortunately, the solution is quite easy, enter the following command on a console window:
evolution --force-shutdown
It seems as if Evolution runs into an error at startup from time to time.
