Mozilla Sunbird is now installable by using Synaptic or apt-get. This is the recommended installation method for most users.
Here's an easy, straight-forward install of Mozilla Sunbird.
Open a terminal
We're going to install it to the /opt directory, so:
Then download Sunbird
Now extract Sunbird to a folder named sunbird in /opt
sudo wget ftp://ftp.mozilla.org/pub/mozilla.org/calendar/sunbird/releases/0.7rc3/linux-i686/en-US/sunbird-0.7rc3.en-US.linux-i686.tar.gz
This gives ownership of the sunbird directory to root.
sudo tar -xvf sunbird-0.7rc3.en-US.linux-i686.tar.gz
Now make a script to redirect to sunbird folder in /opt
sudo chown -R root:root /opt/sunbird/
In the document that opens, copy this into it:
sudo gedit /usr/bin/sunbird.sh
Save and close the document.
Now make the script that was just made executable
Now create a entry in the appilcations menu
sudo chmod +x /usr/bin/sunbird.sh
In the document that opens, enter:
sudo gedit /usr/share/applications/sunbird.desktop
Save the document and enjoy.
