Fixing UEFI Secure Boot problems on Ubuntu 14.04

Unfortunately the mess that is UEFI Secure Boot still causes issues on some hardware. In my case it’s a Toshiba Z930 Ultrabook. I have documented the procedure to get it working here.

However it turns out that there is no ‘Trusty’ release for the boot-repair utility. The fix is relatively easy.

sudo vim /etc/apt/sources.list.d/yannubuntu-boot-repair-trusty.list
#change the following line from 'trusty' to 'saucy'
sudo vim /etc/apt/sources.list.d/yannubuntu-boot-repair-trusty.list

You can then just finish with
sudo apt-get update
sudo apt-get install -y boot-repair && (boot-repair &)

Another option is to boot off a USB image (or CD) created from http://sourceforge.net/p/boot-repair-cd/home/Home/.
