This appears to be the same as bug #1694986.

Do you remember being prompted previously about turning off SecureBoot? Did you elect not to turn off SecureBoot? Or, did you choose the option to disable SecureBoot, but not confirm this selection on reboot?

[José Antonio Sanchez (jasanchezgdu)]

SecureBoot was disabled when the pc started. I did apt-get update and
the system asked about SecureBoot preferences; after updating and reboot
the issue was solved.
