Dear Steve, thanks for your reply. When you wanted me to apport-collect 1799767 once more, shim-signed wasn't installed because I had mad some experiments to solve the problem by myself. So I installed it again to do apport- collect 1799767 once more, but the effect is still the same.
And to clearify that: When I enable CSM in BIOS there is no secure boot but when I disable it, I have secure boot. And as a news: I tried the day before yesterday to set CSM to "auto" and SecureBoot is working with that configuration as well. Only setting to "CSM=enabled" the system doesn't boot in secure mode. You asked if I am sure, that it was "shim-signed 1.37~18", but I can not tell, because normally I do not look at the details, when an update will be installed. I just install it when Update-manager means i should. I trust Ubuntu in that point. I normally install the updates close to the time when they are published. Maybe some days later. -- 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
