Public bug reported:
Tried a clean install of 16.04 from a USB stick in UEFI mode. Got a warning,
that another system (Win10) was installed on another disk in legacy mode and
might not boot, if I used force UEFI mode. Commenced with forced UEFI install
and at the end it stated:
errors were encountered wjile processing
grub-efi-amd64-signed
shim-signed
E: Sub-process /usr/bin/dpkg returned an error code (1)
info: Calling 'apt-install grub-efi-amd64-signed' failed.
But I guess that's in the logfile as well.
A sudo apt-get install grub-efi-amd64-signed seems to have been successful. But
I'll have to reboot to see. Also I did sudo apt-get install shim-signed.
Hope you can find the bug. If you can't I'll gladly assist you trying to
recreate the same situation using an ssh oder whatever you prefere.
