How To Fix unterm: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu unterm is provided by libvterm-bin package.

libvterm-bin is:

An abstract C99 library which implements a VT220 or xterm-like terminal emulator. It doesn’t use any particular graphics toolkit or output system, instead it invokes callback function pointers that its embedding program should provide it to draw on its behalf. It avoids calling malloc() during normal running state, allowing it to be used in embedded kernel situations.

This package contains utility programs that demonstrate libvterm.

sudo apt-get -y install libvterm-bin

This command might take some time to finish depending on your machine internet connection.
