well, folks, not to run into misunderstandings:
Everything was working, got happily squirrel-sql and databases working again. Then started with my test environments in VirtualBox, 2of 3 also working well. Then I started laptop this morning, got another update message and started update-station. It found about these 360 (?) packages for GhostBSD 26.1 (not in VirtualBox, the "real" system), update process went trough, got that little window to restart system and it went till the login screen and then stuck. while booting, I could catch some of the errors (mentioned above), before system got stuck (no switch to terminal possible as well) then I got the white field to put in password, but no keyboard or mouse reacting!
So always have to switch back to boot environment backup 3 to get normal booting and login, but here now stuck with a complete fresh installation and all configuration and no booting into desktop possible. How can I get back to a normal boot process without loosing all fixed configurations or need to re-install again?
Everything was working until I clicked on that update button.
