  • 772

Strange update error appeared while upgrading all other updates setting up fine just this two: grub-efi-amd64-signed/bionic-updates 1.93.2+2.02-2ubuntu8.1 amd64 [upgradable from: 1.93.1+2.02-2ubuntu8.1] unattended-upgrades/bionic-updates,bionic-updates 1.1ubuntu1.18.04.1 all [upgradable from: 1.1ubuntu1]

  1. Ok, this error appeared because grub was tried to make changes to unencrypted file.

    To fix this issue you have to add following line: GRUB_ENABLE_CRYPTODISK=y in to a file /etc/default/grub

    After this everything updates as it should.

    Don't know why this error appear from the start.

    [EDITED]

    If you fix this error as I did, it will breake your GRUB loader, ad you gonna heave to restore it.
