Summary: Reboot to GRUB2 command line after upgrading to Ubuntu
20.04 LTS
Product: neon
Version: unspecified
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: neon-b...@kde.org
Reporter: m...@calabretta.id.au
CC: j...@jriddell.org, neon-b...@kde.org, sit...@kde.org
Target Milestone: ---
SUMMARY
After upgrading to Ubuntu 20.04 LTS, reboot goes to the GRUB2 command line with
no indication of why the boot failed.
STEPS TO REPRODUCE
1. Upgrade from Neon User Edition 5.19 to Ubuntu 20.04 LTS using the
instructions provided at https://community.kde.org/Neon/FocalUpgrades
2. Reboot (as normal part of the upgrade).
OBSERVED RESULT
Reboot fails, dropping back to GRUB2 command line.
EXPECTED RESULT
Normal reboot.
SOFTWARE/OS VERSIONS
Linux: 5.4.0-48-generic
KDE Plasma Version: 5.19.5
KDE Frameworks Version: 5.75,0
Qt Version: 5.15.0
ADDITIONAL INFORMATION
Architecture: x86_64
Dell Latitude E6530.
GRUB2 package versions (from dpkg -l):
grub-efi 2.04-1ubuntu26.4
grub-efi-amd64 2.04-1ubuntu26.4
grub-efi-amd64-bin 2.04-1ubuntu26.4
grub-efi-amd64-signed 1.142.6+2.04-1ubuntu26.4
At the GRUB command line, 'echo $prefix' reports /EFI/ubuntu.
Running 'strings -a' on /boot/efi/EFI/BOOT/BOOTX64.EFI confirms that this
string is hardcoded into the executable. Likewise, for
/boot/efi/EFI/neon/grubx64.efi. Both are copies of
/usr/lib/grub/x86_64-efi-signed/grubx64.efi.signed from the
grub-efi-amd64-signed package.
The /EFI/ubuntu directory does not exist, instead replaced by /EFI/neon.
Re-running 'grub-install' did not fix the problem.
At the GRUB command line, the following effected the boot:
set prefix=($root)'/EFI/neon'
configfile $prefix/grub.cfg
I have implemented a workaround by creating /boot/efi/EFI/ubuntu/ and copying
over grub.cfg and grubx64.efi from /boot/efi/EFI/neon/.
