I installed Discourse in a Ubuntu 18.04.1 LTS VM on our Hyper-V server.
The initial setup works and I get to the point where it is supposed to send the activation email and that failed.
I edited the SMTP settings in app.yml and did a
./launcher rebuild app. This fails with the following error message
/usr/bin/docker: Error response from daemon: error while creating mount source path '/var/discourse/shared/standalone': mkdir /var/discourse: read-only file system.
There does not appear to be a
/var/discourse/shared/standalone directory at this point.
