I'm trying to install virtualmin 6.0.3 on a Digital Ocean Ubuntu 16.04.3 droplet using the --minimal flag. The installation proceeds until step 7 of phase 3, which is ProFTPd configuration. Installation halts after this error:
[7/17] Configuring ProFTPd █▒▒▒▒▒▒

Any ideas, or anyone with a similar issue?
