Servers imaged with OPS-21.06.1 Key or reimaged with RETAIL10-21.06.1 Key Break the boot manager after an “apt upgrade”

Issue:

Linux servers originally imaged with the manufacturing OPS-21.06.1 Key (which introduced 20.04 OS) or reimaged with the RETAIL10-21.06.1 Key break the “rEFInd” boot manager after running ‘apt upgrade’.

Root Cause:

The fundamental issue is that the apt upgrade is updating the grub bootloader and overwriting the “rEFInd” boot manager with a new default (“fallback”) boot manager.

Workaround:

To remediate an existing system:

PROCEDURE (A). If C-Series Standard or C-Series Pro Server:

1. Boot the system and watch for:

  • Failed to open \EFI\BOOT\grubx64.efi – Not Found
  • Failed to load image \EFI\BOOT\grubx64.efi: Not Found
  • start_image() returned Not Found, falling back to default loader
  • Failed to open \EFI\BOOT\grubx64.efi – Not Found
  • Failed to load image \EFI\BOOT\grubx64.efi: Not Found
  • start_image() returned Not Found

2. Press the “Enter” key.

3. Press the “Up Arrow” key three times (3x).

4. Press the “Enter” key again.

5. Wait approximately 10 seconds. The system should boot into the Linux OS as normal.

6. If for any reason you are unable to successfully perform the above instructions, you may be forced to re-image the system with the existing RETAIL2004-21.06.1 Key.

WARNING: The previous step WILL result in the LOSS of the system configuration.

PROCEDURE (B). All other models of servers:

1. Boot and watch for the “GNU GRUB version 2.04” menu to appear with the following choices:

  • Ubuntu
  • Advanced options for Ubuntu
  • EFI Firmware Settings
  • Boot rEFInd

2. Press the “Up Arrow” key three times (3x) to highlight “Ubuntu”

3. Press the “Enter” key. The system should boot into Linux as normal.

4. Install ​http://artifactory.exacq.org/artifactory/seg-local/exacqdeploy/21.09.x/master/103/exacqdeploy_21.09.103.0_all.deb

5. Reboot the system and the graphical boot menu should then be available.
