Bug Description
I've been running Ubuntu on a Lenovo ThinkPad X240. I initially installed 14.10 when I got the machine in January. I then upgraded to 15.04, and on Monday evening (late December 14) I upgraded to 15.10. I rebooted once right after the update to make sure some postfix and opendkim configuration changes I made worked correctly after rebooting.
Then between Monday evening and Friday evening (December 19) there were a bunch of system updates that I installed. On Friday evening I decided to reboot to boot into the updated kernel. (There were also grub updates in that interval.)
When I rebooted, the laptop said:
Secure Boot
Image failed to verify with *ACCESS DENIED*
Press any key to continue.
See the image (posted by somebody else) of this error in http://
I had to disable secure boot to make the system boot.
Based on the discussion in http://
I'll attach a list of the system updates that were applied in the interval between the successful boot and the failed one from /var/log/dpkg.log . Note that the log is in UTC but my description above ("evening", etc., is in UTC-8, so the evening of December 14 is actually around 07:00 UTC on December 15). Note that this log contains a grub update, two kernel updates, and the removal of the first of those kernel updates via apt-get autoremove.
