Since today, I encounter this error message whenever I boot Ubuntu, and it won't let me boot Ubuntu.
[ 0:000000] [Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0x52 (or later) ... BusyBox v1.22.1 (ubuntu 1:1.22.0-ubuntu2) built-in shell (ash) Enter 'help' for a list of built-in commands (initramfs) _
and I am now stuck at the BusyBox
I'm guessing I have to update the microcode, and I couldn't figure out how to do this as I can't even boot Ubuntu. The error message appears after it asks me to enter the pass-phrase for my encrypted hard drive.
Before this it also gives me the error message
Error: environment block too small Press any key to continue.
I don't want to reinstall Ubuntu from scratch, as I still hope to get to the data I have on the encrypted drive. I have also attempted to access the encrypted drive booting from the live USB, but received errors when attempting to access/mount it. (
mount: wrong fs type, bad option, bad superblock on /dev/mapper/ubuntu--vg-root)
A couple of days before this happened, I had installed the latest updates as suggested to me by the Ubuntu Software Center.
