I have this issue too with 16.04 beta 2 Initially I tried the 'disable SecureBoot' option, but after trying again with this option unchecked I still see the error.
I see this line in syslog: ubuntu ubiquity: Failed to request new SB state -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1567445 Title: ubi-prepare failed with exit code 255 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1567445/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
