Development install on Ubuntu 18.04 LTS

I just successfully installed Discourse into a VirtualBox instance of Ubuntu 18.04 LTS Server edition. Here are the things I had to do to get it working conveniently from my host machine.

I followed these instructions for the developer advanced install.

discourse/ at master · discourse/discourse · GitHub

1.The instructions seem to assume an earlier version of Ubuntu in one place.


E: Package ‘python-software-properties’ has no installation candidate


take out “python-software-properties”

sudo apt-get install software-properties-common

2. bundle install failed

To get “bundle instal” to work I needed to execute

sudo apt-get install libpq-dev

3. Getting mailcatcher to work so I could view it from the host

I had to run mailcatcher this way:

mailcatcher --ip=

4. Being able to use SSH to get into the host

I found it convenient to SSH into the Ubuntu 18.04 guest so I could copy/paste. I used this tutorial to get it working.

Is this install intended for development purposes?

Your title doesn’t indicate it, but as production installs require docker I’ve updated the title so that others aren’t misled. I’m also recategorizing as #dev as #installation is exclusively for the docker install.
