How to install Virtualmin on Ubuntu Linux

  1. First install Ubuntu 8.04-1 LTS. It’s the only version VirtualMin supports.
  2. Towards the end of the install, Ubuntu will ask what servers you want to add. Only choose OpenSSH server. No apache, bind, ftp, etc. ONLY OpenSSH.
  3. Reboot, login, and get the file from the network.
  4. Run >
    sudo sh

    and type in your password.

  5. In /etc/hosts, add the following line after any search and/or domain statements (not required), and before any other nameserver statements:
  6. Login to https://Virtualmin.Your.IP:10000/ and verify the Virtualmin configuration under Virtalmin->System Settings->Re-Check Config.
  7. Edit /etc/dovecot/dovecot.conf and change the following settings:
    disable_plaintext_auth = no

    Find the section —
    auth default {
    –and change mechanisms to at least the following:

    mechanisms = plain login

    At the end of the section–
    protocol pop3 {
    –change/add the following setting:

    pop3_client_workarounds = outlook-no-nuls oe-ns-eoh
  8. # edit /etc/default/saslauthd and set OPTIONS like this:
    OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd" 
  9. # run this command as root:
    sudo dpkg-statoverride --add root sasl 710 /var/spool/postfix/var/run/saslauthd
  10. # add the postfix user to the sasl group:
    sudo adduser postfix sasl
  11. Configure ProFTPd
    In /etc/proftpd/proftpd.conf, chroot users by upcommenting the following line (don’t forget the tilde ~ at the end of the line):

    DefaultRoot                     ~
  12. Reboot

You should now have a working Ubuntu system with Virtualmin fully loaded. Make a clone of this clean system!
