Title:
Secure boot fails after upgrade to 15.10
Status in linux package in Ubuntu:
Confirmed
Bug description:
I was previously running XUbuntu 15.04 on my Asus UX303L laptop.
The configuration is dual boot with windows 8.1.
I ran the upgrade via the software updater and it proceeded normally.
Upon reboot, I got a red screen saying that something was wrong with
secure boot and it had to be fixed in the BIOS.
In BIOS, I disabled Secure boot and was again able to access XUbuntu.
I would like to re-enable secure boot, but cannot.
I am happy to help debugging in any way - I am a qualified computer
scientist.
Sincere thanks,
Bob
