Output of apport-collect now is ... Package shim-signed not installed and no hook available, ignoring Gtk-Message: 21:00:40.534: GtkDialog mapped without a transient parent. This is discouraged ...
And yes, it's true, at the moment it is not installed and the behaviour is as I described first. But I'm sure, that the behaviour was the same when shim-signed had been installed some days ago. If you want, I can install it, try reeboot with CSM enabled and with CSM disabled and tell, what I have found out then. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1799767 Title: grub menu not showing with SecureBoot enabled after update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim-signed/+bug/1799767/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
