Wrong signature on EFI Bios after dist-upgrade
Asked by
Vincent LESCAUT
Hello,
I am running Ubuntu 14.04. This week, I ran apt-get dist-upgrade, as there were efi-bios and grub updates pending.
Update ran fine, but after reboot my EFI Bios complains that the signature is wrong and it refuses to run Grub.
To access Grub, I must disable the security in the Bios.
Using Google, I can just find users facing a similar issue upgrading from 13 to 14.04, but they got an error message, not a wrong signature.
It seems the signature has not been updated after the grub update.
Who can help me ? I'd rather prefer to enable security on Bios.
Thx for your feedbacks
