How to *completely* remove tigervnc server from Ubuntu 22.04?

[Ralf Mardorf]

PS:

I don't know what happens to installed dependencies.

tigervnc-common is a hard dependency
tigervnc-tools  is a recommended dependency

see

https://tracker.debian.org/pkg/tigervnc
https://packages.ubuntu.com/jammy/tigervnc-standalone-server

you might need to purge

  tigervnc-standalone-server

and

  tigervnc-common

and probably other related packages containing configurations related to
tigervnc .
