Just two days ago (Jun 18, 2019), I was prompted to allow a routine Ubuntu update. After update finished and reboot, I'm no longer able to boot into Ubuntu. Specifically, I was taken to the Grub screen, select 'ubuntu', then face a purple screen, nothing happens afterward.
There's this thread, addressing I think the same issue. My question is :
Is it possible to roll back the Intel microcode change without doing what is suggested there,
sudo apt-get install intel-microcode=3.20180312.0~ubuntu18.04.1
Reason this is not possible is, in terminal mode, I have no access to internet.
dpkg -iinstall that. (apt-get will use
dpkgto do actual install once it's got everything.. ie. what your post talked of really as a fix just by-passing
