[Bug 1777101] Re: I was updating from 14.04 to 18.04 ... the installer told me that grub did not install properly and that I can not login. What do I do now?

[Michael Lempenau]

I tried to log off ... didn't work.  Tried to shutdown normally ...
didn't work.  So I did a hard shutdown and then it booted into 14.04.
So I initiated a new install.  At the point where it asked me if I
wanted to install alongside 14.04 ... this time it listed 18.04 as well.
I chose to wipe the disk (everything was backed up) and do a clean
install.  It worked fine.  Something must be wrong with the install
program for installing alongside another installation.  Anyway I'm
happy.  Any questions let me know.
