Installing Ubuntu

You can either install Ubuntu by downloading the ISO file and creating a bootable device and create a disk partition, OR you can download the Windows Installer and install directly from windows.

If you have another operating system already, it would be nice to backup your files (just in case). If in case you you blow up you Windows while trying to install Ubuntu (happened to me the first time I tried), you can download Windows from IIT Bombay's MS Store, if your from IIT Bombay. If your not from IIT Bombay, then God help you!

You then also need to set up proxy settings if you are within the IIT Bombay network and repository settings if you need to install softwares and packages fast:

Coping with Netmon

Ubuntu Proxy Settings

Following is the way to get Ubuntu working under IITB proxy with apt-line installation

• For Ubuntu 11.04 and below, go to network proxy.
• Set proxy either netmon.iitb.ac.in port 80 or www.aero.iitb.ac.in port 8081 for all protocols.
• In exclusion list, add *.iitb.ac.in and 10.0.0.0/8.
• Apply system wide
• For Ubuntu 11.10 and above, go to Network from the dash. Network Proxy should be under it. Set proxy as above.

Now some files have to be edited:

• Open terminal.
• Type

  sudo gedit /etc/apt/apt.conf /etc/environment /etc/wgetrc 

• This will open 3 files in gedit
• If you are using aero proxy, P=http://www.aero.iitb.ac.in:8081/ . If you are using netmon, P=http://ldapusername:ldappassword@netmon.iitb.ac.in:80/. Use HTTP protocol only. No https://.... or ftp://....
• The /etc/apt/apt.conf should look like

	Acquire::http::proxy "P";
	Acquire::https::proxy "P";

	#### P is from previous step
	#### Notice: No FTP proxy
				

• For /etc/environment,

	#### Something about PATH variable here

	http_proxy=P
	https_proxy=P
	ftp_proxy=P
				

• For /etc/wgetrc, Uncomment the proxy lines and replace the values by value of P. Uncomment the line use_proxy=on
• Save files, restart Terminal and you are done!!!

Ubuntu Repository Settings

To use IITB apt software repositories in ubuntu, follow the steps:

• Make sure you have no FTP proxy in /etc/apt/apt.conf file. If you have followed proxy instructions from this guide, you don't need to do anything.
• Make a backup of /etc/apt/sources.list if you want to.
• Open Terminal.
• Type & hit enter

sudo gedit /etc/apt/sources.list

• A file will open in gedit. Replace all the contents by

	######### Warning: Instead of maverick, use the name of your distribution in following lines

	deb ftp://ftp.iitb.ac.in/os/ubuntu/archives/ maverick main restricted
	deb-src ftp://ftp.iitb.ac.in/os/ubuntu/archives/ maverick main restricted

	deb ftp://ftp.iitb.ac.in/os/ubuntu/archives/ maverick-updates main restricted
	deb-src ftp://ftp.iitb.ac.in/os/ubuntu/archives/ maverick-updates main restricted

	deb ftp://ftp.iitb.ac.in/os/ubuntu/archives/ maverick universe
	deb-src ftp://ftp.iitb.ac.in/os/ubuntu/archives/ maverick universe
	deb ftp://ftp.iitb.ac.in/os/ubuntu/archives/ maverick-updates universe
	deb-src ftp://ftp.iitb.ac.in/os/ubuntu/archives/ maverick-updates universe

	deb ftp://ftp.iitb.ac.in/os/ubuntu/archives/ maverick multiverse
	deb-src ftp://ftp.iitb.ac.in/os/ubuntu/archives/ maverick multiverse
	deb ftp://ftp.iitb.ac.in/os/ubuntu/archives/ maverick-updates multiverse
	deb-src ftp://ftp.iitb.ac.in/os/ubuntu/archives/ maverick-updates multiverse
				

• Save the file.
• Run sudo apt-get update in Terminal. You are done.
• Now you can install softwares from IITB repositories. They are very fast as compared to HTTP repositories.
