package lvm2 2.03.07-1ubuntu1 failed to install/upgrade: installed lvm2 package post-installation script subprocess returned error exit status 1

[wistle]

I upgraded my system from 18.04 to 20.04, everything seemed to work fine for a day or two. This morning I booted into a very old version of my desktop with most of my applications and files missing. I found that LVM somehow failed/uninstalled, since my home partition is on LVM, it had the latter effect.
Upon trying to install LVM, I got this error, however, LMV is running and I have my desktop and files back. Just concerned that this might happen again.
