I just installed it on my test virtual machine of mint 20 to verify it still works.

Copy and paste, and run these commands one at a time;
add the key
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 382003C2C8B7B4AB813E915B14E4942973C62A1B
add xenial repo
sudo add-apt-repository "deb http://ppa.launchpad.net/nemh/systemback/ubuntu xenial main"
update the package list
sudo apt update
then install systemback
sudo apt install systemback

Systemback should now be in your menu

Open it, click on "live system create"

Would really appreciate some help on this, pls.

According to their website Systemback author stopped its development in 2016, so it probably isn't compatible with the current version of LM. You don't need to create an iso all you need to do is create an image file. You can use Rescuezilla to do that.

Looks like 'mate-polkit-common', a dependency or otherwise, has a problem with its files list formatting, which is something its maintainer should be addressing.
