Brief notes on installation, setup and other tasks in the Ubuntu world

Upgrading to Ubuntu 12.04 LTS

leave a comment »

I will be upgrading to Ubuntu 12.04 LTS from the previous LTS (long-term stable) version, Ubuntu 10.04. To so this, I will create a bootable USB stick with 12.04 LTS. To start, I download the current iso from Canonical — download Ubuntu here. The iso file can be used to create a CD or USB stick for trying out Ubuntu before installing, as well as the actual install. I have 4GB RAM, so I download the 64 bit version: ubuntu-12.04.1-desktop-amd64.iso (~694MB).

Creating a bootable USB stick

Creating a USB stick in Ubuntu 10.04 is very easy, following instructions here (instructions for Windows and OSX machines are also available). These instructions assume Ubuntu 12.04 is being used, so the specifics are a little different for my Ubuntu 10.04 machine:

  • Insert a USB stick (4GB or more is recommended)
  • Find the Startup Disk Creator. In Ubuntu 10.04, this is in the menus: System > Administration > Startup Disk Creator.
  • Under Source disk image, at the top, click Other… and select the iso downloaded above.
  • Under Disk to use, choose the USB stick.
  • Choose your preference for handling files created with this USB and click Mark startup disk.
  • You should be prompted for your password before the process begins and be notified of ‘Installation Complete’ when things are done.

Installing

This part is fairly simple — boot from the USB stick (you might need to muck with BIOS settings to get this working). You can test things out at this point, as Ubuntu runs from the USB stick without installing. If you decide to install — back up all information on your computer before moving forward. Also, make sure that you are plugged in for power and have an active internet connection. With that done, click install (there should be an icon on the desktop). The install is fast and painless. There will be many updates after the install.
