2.4 Reverting to grub 2.02-beta2-9ubuntu1.6_amd64
+ You can start synaptic "sudo synaptic" and force the previous version of
+ these packages (Package->Force version...) and lock that version
+ (Package->Lock version...).
+
+ I did it manually as described below:
+
Steps:
1. Download the following files (from https://launchpad.net/~ubuntu-
security-proposed/+archive/ubuntu/ppa/+build/8443424) in a separate
(newly created) folder
grub2-common_2.02~beta2-9ubuntu1.6_amd64.deb
grub-common_2.02~beta2-9ubuntu1.6_amd64.deb
grub-efi-amd64_2.02~beta2-9ubuntu1.6_amd64.deb
grub-efi-amd64-bin_2.02~beta2-9ubuntu1.6_amd64.deb
grub-efi_2.02~beta2-9ubuntu1.6_amd64.deb
2. From that folder install the deb files with the following command:
sudo dpkg -i *.deb
