[Bug 1788727] Re: upgrade crashing due to unsigned kernels

[Jim Aird]

Sandi, I hope this is the correct procedure reporting via you. Thanks
for the email. My HP system seems a little different than yours, I
finished up with the two latest kernels and a warning that I also had
an old kernel that was not of the secure boot (efi) variety.

I deleted the old kernel, to find later that it was the old kernel
that worked best occasional.

I cannot directly install Ubuntu 20.18 from a USB stick, it wont even
load up. I managed to install Ubuntu 17.10 then upgrade to Ubuntu
20.18

The first non efi kernel was 4.13.0-21-generic. I upgraded from Ubuntu
17.10, and am informed that a non efi kernel 4.13.0-46-generic has
appeared and prevents completion, I have deleted this kernel. After
aprox 20 boots I gave up trying to get into the computer. (there is no
logic in getting the computer to boot up, the more I try the less
chance of success).

Next day

Five attempts booting with kernel 4.15.0-3-generic failed, third
attempt with kernel 4.13.0-21-generic success

A crash happened on the HP pc this morning and I was asked if I could
supply any data, hence this email. I hope this information reaches all
concerned and is of use.

Regards Jim
