Public bug reported:
when installing upgrade from 16.04 to 18.04 on ubuntu i got loads of errors
tat i dont understand:
my system has uefi secure boot enabled in the firmware so the following kernels
present in the system were unsigned, 5.5.1-050501-generic , then the rest of
the message tells me grub wont be updated till these kernels are replaced with
signed kernels.
thats one thing
sems to me the easiest thing is to back up files and the wie the system
and install the latest ubuntu from fresh. Ive been getting lots of
issues from updates to 16.04 with a regular unspecified error every
logon which pops up a message window which is totally generic.
