The repository currently only provides packages for long-term support (LTS) releases; Kinetic is not an LTS release. You can try to use a DEB package for the nearest LTS release (Jammy in your case) from the packages page, or build the program manually as described in the user manual.

I tried building from source by following the build instructions

I get the error when I run the program. No clue what to do.

I tried this but I am getting the error saying "unmet dependencies"

On your login screen, after you choose the user and the password entry appears, there should be a gear button that lets you choose X11 (Xorg) session.

If you use a distro other than Ubuntu, the login screen may look different, but in general there should be an option that allows you to choose an Xorg session.

The PPA now has builds for non-LTS releases. Not for Kinetic, however, as it reached the end of life, but for Lunar and newer. Run:

sudo apt update
sudo apt install dpscreenocr
