[Bug 1904263] Re: Writing GRUB to boot device failed

[LinuxBreaksEasy]

Hi There,

I took a snapshot, then I went ahead and clicked 'Continued without
installing Grub' and let the computer restart after the update.
Everything restarted and came back up just fine, so it was okay to just
continue in my case. Everything seems happy now. Not sure what the
actual underlying issue is/was but the system is running stable.
