RT on Debian 9.4

I’m having trouble installing RT.
I tried many ways to installs, following documentation but I got several difficulties along the way.

I would like a help step-by-step installation for linux dist- Debian 9.4 last-stable

A bit more information might help folk help you such as:

  • What version of RT are you trying to install?

  • Are you using the Debian packaged version (ie apt-get install request-tracker4) or installing from source?

  • What difficulties have you encountered?
