Comment 1 for bug 1990738

I think I fixed my issue. I downloaded the libssl from Debian & installed it with dpkg.

sudo dpkg -i libssl1.1_1.1.1o-1_amd64.deb

A dpkg -l libssl1.1 confirmed it was installed. After confirmation, I was able to run a apt-get update and apt-get upgrade and I got the following output:

$ sudo apt-get update

I'm hesitant whether or not I should install Grub Customizer. Please advise.
