Status in linux package in Ubuntu: Confirmed Bug description: Hello, I didn't exactly know which category to slected during bug report submission, but after I updated my Ubuntu 19.10 installation yesterday, whenever I press restart either through gui or terminal the system boot into blinking underscore immediately after bios post screen. Not even grub menu shows up. I have to shutdown the system, then turn it on again to fix the problem. The system boot normally from a shutdown. I have already tried clean installing Ubuntu 19.10 but the problem returned after installing the updates by executing sudo apt upgrade command! I guess this issue happens after upgrading the linux-firmware package to the latest 1.183.2 version.
