+## A2SERVER
+
+ These steps cover how to install Ubuntu Server Linux into your empty virtual or real machine. (The instructions are similar, but may vary somewhat, for Debian Linux.)
+
+* Download [Ubuntu Server 12.04 LTS][1], and burn it to a CD if
+  installing on a real machine; otherwise, attach the download to your
+  virtual machine\'s CD/DVD drive.
+
+* Click Start.
+
+* Answer all the region related questions and choose to Install Ubuntu
+  Server.
+
+* For hostname, enter *a2server*
+
+* Under Partition Disks, choose \"Guided - use entire disk\" (no LVM).
+
+* Choose SCSI1 (or whatever other disk appears), and (two screens later)
+  confirm \"Write the changes to disks.\"
+
+* If you are installing Debian, and are prompted for a domain name or
+  the root user password, leave them blank.
+
+* Enter *user1* as the full name for the new user, and as the username
+  for your account
+
+* Choose *apple2* as the password, verify by retyping, and then confirm
+  weak password
+
+* Choose not to encrypt your home directory
+
+* If you require an HTTP proxy, enter it, or leave it blank if not.
+
+* Choose yes to Install the GRUB boot loader to the master boot record
+
+* Choose no automatic updates
+
+* Choose OpenSSH under Software Selection (and, for Debian, Standard
+  System Utilities)
+
+* Click Continue to reboot
+
+* When prompted, log in with username *user1* and password *apple2*.
+
+* If you installed Debian rather than Ubuntu, type:
+  
+  ```
+  sudo sed -i '0,/-eq 0/s/-eq 0/-ge 0/' /etc/profile
+  ```
+
+* When you\'re back at the prompt, type `sudo shutdown -h now` which
+  will turn off the (virtual) machine.
+
+* Recommended: If you are using a virtual machine, take a snapshot you
+  can return to this point if necessary.
