If you were presented with this option, it was because you had already selected to install third-party drivers that would require disabling Secure Boot. > Further research showed me that all the OS needs is for Secure Booting > to be turned off in BIOS, so, erm... why didn't they just get the user to do > that ahead of time Because there is no consistent user interface for disabling Secure Boot in the firmware, making this impossible to provide clear directions for all users to follow. > Anyway, my question: Now that I have this "Booting in insecure mode" message > in my boot process, how do I get rid of it.

If you want to re-enable SecureBoot validation within shim, you can do so by running this command, then rebooting to confirm the change: sudo mokutil --enable-validation However, doing so will render any third-party kernel drivers (e.g., nvidia video drivers) inoperable on your system which may result in a degraded experience. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1590668 Title: Shim now reports "booting in insecure mode" regardless of BIOS setting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1590668/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
