Hickups during upgrade from 25.7.7_4 to 25.7.8

[ednt]

In a master slave environment on old HP Server hardware I see the following:

Slave:
During the update a warning window appeard: something went wrong, please check the log files.
But the update was completed and the Server rebooted at the end.

Master:
The same warning window appeared and when the reboot should happen it jumped back to the dashboard,
without a reboot.
When I againg clicked on check for updates the window 'reboot is active' appeared, but no reboot was in progress.
I pressed ctrl+alt+del for a reboot.
It took long for shut down, but rebootet succesfully.

I just heard from a colleague that he saw also the warning window but the update worked. (like on our slave)

Only for information.

P.S.: at the moment I see 'pfr_update_stats: assertion failed.' on the master console
