The Initial OS Install of An Image

No I'm not going to tell you how to follow the installation procedure for one of the many ISO images available at "http://mirror.cs.uwaterloo.ca/ubuntu-releases/". Internet search will provide

A few suggestions I do have are:

1. If your looking to exactly match the CSCF deployed systems,

   When you get to the "Updates and other software" screen, in the "What apps would you like to intall to start with?" area select "Minimal Installation".

2. If you have two monitors (dual headed)

   Turn one of them off until the install is done. You can then add the second monitor using a "TwinView" Configuration (NVidia graphics card) in your "X Server Settings" (look in "System" -> "Administration" menu) after the install is finished.

3. If the setup process does not detect all of the hard drives. It is likely that the motherboard supports on-board "SATA" Raid (winmodem styled cheap raid controller) that "dmraid" doesn't recognize properly (it doesn't seem to matter if the disk controller BIOS setting is SATA, RAID or AHCI). You need to remove Linux dmraid package from the install process.
    

   Boot the system with the "Try Ubuntu ..." selection and enter in a terminal window:

   sudo apt-get remove dmraid

   Now perform the setup by clicking the "Install Ubuntu ..." desktop icon (upper left corner of screen).

4. If you're going to be connecting the host to one of the CSCF AD domains

   Make sure any local user accounts you create are unique (suggestion is to add a unique prefix like "local-" or "my").

5. Check "/etc/hostname" and "/etc/hosts"

   Make sure the host name is the Fully Qualified Name minus whatever your official domain-name is, e.g. "cs.uwaterloo.ca".

So go ahead and do the base install, stopping just after the first reboot.

Updating the Apt Repository Sources to use the CS sponsered local mirror as well as the medibuntu and wine repositories.

1. With the support of University of Waterloo School of Computer Science, the CS Club provides an official Canadian mirror (mirror.csclub.uwaterloo.ca) of many sites.

   CSCF setup makes use of this Ubuntu repository as their main Apt sources configuration file.

   Make sure this hosts "local apt key trust" has the ca-certificates package installed:

          sudo apt-get install ca-certificates
        

   Update /etc/apt/sources.list

          wget -q -O - \
            https://cs.uwaterloo.ca/cscf/internal/infrastructure/setups/os/ubuntu/UW-CS-common/etc/apt/sources.list
              | sed -e "s/CodeName/`lsb_release -c -s`/"       \
              | sudo -s tee /etc/apt/sources.list.d/uwcs-depot.list > /dev/null
        

   Update apt's local database, checking output for problems with new setup:

   sudo apt-get update

2. Create /etc/apt/sources.list.d/canonical_partner.list

   Use this repository for up-to-date versions of Acroread, Flash, Skype, UEX, SUN Java, OpenBravo...

   Information from http://www.ubuntuupdates.org/ppa/canonical_partner

   sudo sh -c 'echo "deb http://archive.canonical.com/ubuntu/ `lsb_release -c -s` partner" > /etc/apt/sources.list.d/canonical_partner.list'

3. These packages allow people to easily duplicate the Linux environments used within the Cheriton School of Computer Science.

   Add "depot.cs.uwaterloo.ca" gpg key to the local apt key trust.

   	if [ `lsb_release -sr` \> 22 ]; then 
              wget -q -O - \
                https://cs.uwaterloo.ca/cscf/internal/infrastructure/setups/certs/depot.pub.gpg.key \
   	     | sudo tee /etc/apt/trusted.gpg.d/depot.pub.asc > /dev/null
   	else 
   	   wget -O - \
                https://cs.uwaterloo.ca/cscf/internal/infrastructure/setups/certs/depot.pub.gpg.key \
   	     | sudo apt-key add - 
           fi
        

   Create /etc/apt/sources.list.d/uwcs-depot.list

          wget -q -O - \
            https://cs.uwaterloo.ca/cscf/internal/infrastructure/setups/os/ubuntu/UW-CS-common/etc/apt/sources.list.d/uwcs-depot.list \
            | sed -e "s/CodeName/`lsb_release -c -s`/"       \
            | sudo -s tee /etc/apt/sources.list.d/uwcs-depot.list > /dev/null
        

   Update apt's local database:

   sudo apt-get update

1. Various "uwcs" packages assume that the setup also has access to http://www.medibuntu.org packages.

   Add Medibuntu's repository and recommended packages to your Ubuntu Setup along with the Medibuntu's GPG key to your keyring.

   Information from http://www.medibuntu.org/repository.php

   Create /etc/apt/sources.list.d/medibuntu.list

   sudo -E wget --output-document=/etc/apt/sources.list.d/medibuntu.list \
                http://www.medibuntu.org/sources.list.d/`lsb_release -cs`.list \
        && sudo apt-get --quiet update \
        && sudo apt-get --yes --quiet --allow-unauthenticated \
                                     install medibuntu-keyring \
        && sudo apt-get --quiet update

   Install packages from Medibuntu:

   We also wish to add the following packages. The first will cause many apps from the Medibuntu repository to appear in Ubuntu Software Center (Ubuntu 9.10+) or Add/Remove Applications (versions prior to 9.10). The second will allow users to generate crash reports against Medibuntu packages and submit them to the Medibuntu bugtracker.

   sudo apt-get install app-install-data-medibuntu apport-hooks-medibuntu

   
   

Setup Various OS Services.

1. You should likely double check the "/etc/resolv.conf" setup: [an error occurred while processing this directive]

2. We want to be able to use snmp to monitor this server:

   [an error occurred while processing this directive]

3. Setup NTP: [an error occurred while processing this directive]

Make Sure System Is Up-to-Date With Only the Minimum Packages CS Wants.

Remove packages that cause problems.

blcr-dkms 0.8.2 does not work on kernels newer than 2.6.30. 0.8.4 only works with 2.6.38. If you need this package you must revert to such a kernel, if not, simply remove it. Since blcr 0.8.2-15ubuntu2.1, the blcr-dkms package can be safely removed without wanting to remove libcr0 and openmpi as well, see LP:#1005524.

sudo apt-get -y purge blcr-dkms

We don't want clear text passwords being used for network connections:

sudo apt-get -y purge telnet rsh-server rsh-client
 

We don't want command-not-found:

sudo apt-get -y purge command-not-found command-not-found-data
 

We don't want any packages that tamper with /etc/resolv.conf:

sudo apt-get -y purge resolvconf
 

Nore do we want anything playing with our network setup.

sudo apt-get -y purge network-manager-gnome network-manager-pptp network-manager-pptp-gnome
 

We don't leave games on the servers (sigh):

sudo apt-get -y purge gnome-games gnome-games-data
 

We have a fixed set of Shells and Scripting languages we offer

sudo apt-get -y install uwcs-shells
 

Users expect those shells to be named in /etc/shells:

/bin/ls -1 /xhbin/*sh >> /etc/shells
 

and now make sure everything is up-to-date while accepting the package maintainer's recommendations for companion packages.

sudo apt-get -y dist-upgrade
 

with no extras left laying around.

sudo apt-get -y autoremove

sudo apt-get -y autoclean

reboot
 

OK, so now lets make this host packages a clone of our standard:

Once the system comes back up, login and enter:

sudo aptitude -y --with-recommends install dselect

sudo wget -q -O - \
       https://www.cs.uwaterloo.ca/cscf/software/ubuntu/UW-CS-custom/etc/apt/installed-packages.txt \
     | dpkg --set-selections

sudo dselect install
