Installation problem bundle install

Hi,
would like to test Zammad and I have installed a Ubuntu version 18.04.3. Zammad installation source was Source.
Since there were problems with the GEM file I had to install a newer RVM version (2.6.5).
Now I fail with the following command:

zammad@zamadi:/root$ bundle install --without test development postgres
There was an error while trying to write to /.bundle/config. It is likely that you need to grant write permissions for that path.

Unfortunately Google could not help me. I hope you can help me here :slight_smile:

Thank you

Zammad requires you to use ruby 2.5.5.
Please see: https://docs.zammad.org/en/latest/prerequisites-software.html

This is a dependency issue we proberbly cannot help you with.

If you just want to play around, the easier way would be docker or package installation.

Where i will find the documentation for the package installation?

I used this one https://docs.zammad.org/en/latest/install-source.html#install-from-source-debian-7-8-ubuntu-16-04-ubuntu-18-04
