Chromium already supplies 3 important PPAs (beta channel only contains small version upgrades compared with stable):
Chromium - Stable Channel
Chromium - Dev Development
Chromium Daily Builds
This means there is no need to actually build anything, its already done for you.
You just need to install the PPA on your system and Chromium will be up to date all the time.
Open a terminal and start by adding the PPA
For the stable channel (current version 16)
sudo add-apt-repository ppa:chromium-daily/stable
For the dev channel (current version 17)
sudo add-apt-repository ppa:chromium-daily/dev
For the daily builds channel (current version 18)
sudo add-apt-repository ppa:chromium-daily
After this you need to update your sources
sudo apt-get update
When the sources update is complete you just need to install the chromium-browser package and the desired version will be installed
At last run
sudo apt-get install chromium-browser
source: http://askubuntu.com/a/89065
Note: If you have some problems upgrading the dev or daily channels you may try this:
1. Close all the chromium trays (if you have any open) or close all the procces tree with the system monitor (or just kill the procces with the terminal).
2. Just use one of the channels, don't add the 3 ppa, becuase they'll get stuck. The -sudo apt-get install chromium-browser- is the same for all 3
3. Erase the old Chromium version at ~/.config/chromium/Default (erase all the Default folder). After you erase it run the apt-get install command again.
