Every time I install a new WIP, either from the automatically downloaded service release, or (like just now) a service release candidate, about halfway through the install, a dialog pops ups saying something like “No action was taken because the system needs to be restarted”.
While this dialog is onscreen, the install process, as indicated by the red progress line, stops. The dialog can be dismissed by closing it via the top right X, and then the install process resumes for about 5 to 10 seconds, until the same dialog comes up again.
The install can be completed by simply closing the dialog every time it appears (about five of six times) and I then get the install completed / restart dialog.
After restart, everything is fine, and stays fine until the next install.
This has been going on for some months; I’d like it to stop.
