While doing do-release-upgrade from 22.04 to 24.04, this system encountered an issue during restart(i.e. after installing 24.04 was completed). How do I recover from this issue? The upgrade procedure is given by nixCraft.

This answer by Shai Coleman on Unix & Linux solved my issue. All credit goes to him.

The solution for me was clearing the EFI variables and then disabling secure boot.

On my Asus X556 laptop, I followed the following steps, but they'll vary for each computer:

  • Press F2 during boot to enter the BIOS
  • Press F7 to enabled Advanced Mode
  • Security > Secure Boot > Secure Boot Control: Enabled. You need to enable Secure Boot for access the key management.
  • Security > Secure Boot > Key Management: Reset to Setup Mode to clear all the variables and keys. It should show "No Key" multiple times.
  • Security > Secure Boot > Secure Boot Control: Disabled. Secure boot must be disabled because there are no valid keys.
  • Save and exit
