Title: Updating shim-signed freezes computer during postinstall Status in linux package in Ubuntu: Incomplete Bug description: When performing an update using ubuntu's default GUI tool, during the "configuring shim-signed" message, the computer freezes and needs to be reset. Unfortunately, there is nothing in the system log except for corruption (a lot of null bytes). But I experience these hard freezes regularly, whenever a GRUB or EFI related package is being updated, always during postinstall.

However, for some reason it does not happen with a very similar second machine. This machine does not load the 'efi' kernel module on boot, can this be the reason? [ 0.000000] SMBIOS 2.8 present.
