Using apt-get to install 4Pane
Before you can use the 4Pane repository, you need to tell the apt-get setup that it exists. You do this by adding the appropriate url to apt-get's list of known repositories, /etc/apt/sources.list. You must be the superuser to do this, so either su to root (debian, mepis, PCLinuxOS), or prefix sudo to everything (or do sudo bash) (*buntu).
First you may wish to make a backup of your current settings:
cp /etc/apt/sources.list /etc/apt/sources.list.bak
Then either use your favourite text editor to add the appropriate line, or do (using debian squeeze as an example):
echo "deb http://www.4pane.co.uk/debian/ squeeze contrib" >> /etc/apt/sources.list
The line to add is different for different distros/versions; choose the appropriate one:
Next tell apt about the 4Pane public key (remove the 'sudo' if you've already su'ed):
wget -O - http://www.4pane.co.uk/4Pane.asc | sudo apt-key add -or, rather faster to type:
apt-key adv --fetch-keys http://www.4pane.co.uk/4Pane.asc
You then need to do:
apt-get install 4pane
and 4Pane should be both downloaded and installed.
Alternatively, use an apt-get front end e.g. synaptic to add the repository and do the install.
