When I do sudo apt-get update I see an output like this:

Hit:1 http://security.ubuntu.com/ubuntu focal-security InRelease

E: The repository 'http://ppa.launchpad.net/gnome-terminator/ppa/ubuntu focal Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

What should I do?

At first you have to fix the network or mirror connectivity problems. You can change the actual mirror in the Software & Updates (software-properties-gtk) application

Then remove problematic PPA which does not provide packages for your Ubuntu release, update package lists and install Terminator from official universe repository:

sudo apt-add-repository -r ppa:gnome-terminator/ppa
sudo apt-add-repository universe
sudo apt-get update
sudo apt-get install terminator
