package idle-python3.7 3.7.1-1~18.04 failed to install/upgrade: installed idle-python3.7 package post-installation script subprocess returned error exit status 127

I am not exactly sure what happend. I had started my laptop, and it was stuck on a black screen. I had to force it to shutdown and I guess something went wrong with the OS as when I was trying to start the computer I got a screen full of text on of top rows said TSC_DEADLINE disabled due to errata please update microcode to... something.

I was able to use the Ubunbu advanced options to restore older version of the OS.
