This how-to starts assuming basic minimal installation of Ubuntu 16.04
Now using nano instead of vim

5. Synchronize the System Clock - > SKIP THIS

6. -> service sendmail stop; update-rc.d -f sendmail remove

->You will be asked the following questions:

General type of mail configuration: <-- Internet Site

#freshclam

ERROR: Problem with internal logger (UpdateLogFile = /var/log/clamav/freshclam.log).

7.1 Install Metronome XMPP Server (optional) - SKIPPED

11. Install PureFTPd and Quota

#nano /etc/fstab

Contains : # UNCONFIGURED FSTAB FOR BASE SYSTEM

https://forum.proxmox.com/threads/no-fstabs-after-installing-debian-standard-template.21028/

"They support running on LXC but told me quota is not supported inside LXCs. I can simply skip that step."

So went straight to step 12.

18.2 OpenVZ

Not running OpenVZ so ignores (Olivier ignores too)

A la fin :

1) Change the time zone to Paris : dpkg-reconfigure tzdata

1A)Ensure container option Start at boot checked
