Bug#1024395: Side note : the packages are marked on hold in previous mail because of dual boot with windows bitlocker activated.

[Eric Valette]

If I upgrade EFI components without suspending bitlocker on Windows I 
need to enter the bitlocker key. Very annoying.

So I cannot update normally shim and grub EFI components. There are on 
hold until I know I have disabled bitlocker and can manually upgrade.

As soon as done, I put them again on hold.
