Ocaml stays in system after apt remove and apt purge

Question

I have an Ubuntu 20.04 which i installed in a distant past. For some reason i have OCaml installed on it even though im pretty sure i never used it. Im trying to uninstall OCaml via

 sudo apt-get remove ocaml
 sudo apt-get purge ocaml

But all i get is

Package 'ocaml' is not installed, so not removed

But the OCaml icon still shows in the "Show Applications" option and if i type

ocaml

Im directed to an ocaml session. How can i completely remove it from my system, including the icon? If it helps: the response to

which ocaml

is

/usr/bin/ocaml

Answer 1

You can check which package owns /usr/bin/ocaml with

dpkg -S /usr/bin/ocaml

If no packages own /usr/bin/ocaml, it is safe to delete it by hand.
