Banshee 2.0 just came out, and will be the default music player for the upcoming Ubuntu 11.04 Natty Narwhal release. But if you want to try Banshee 2.0 on Ubuntu 10.10 Maverick Meerkat, you can upgrade with a just a few Terminal commands.
(Note that this will only work if you already have an older version of Banshee installed on your system.)
First, go to a Terminal (the Applications menu, and then Accessories), and type this command:
sudo apt-add-repository ppa:banshee-team/banshee-daily
Enter your password to authenticate, and apt will add the Banshee PPA (personal package archive) to your system’s list of software repositories. Next, use this command to update your system’s index of its repositories:
sudo apt-get update
After the update is complete, use this command to update your system’s software packages:
sudo apt-get upgrade
Note that this command will upgrade every software program on your system that has an upgrade available in the repositories. Finally, type this command:
sudo apt-get dist-upgrade
This will update the final files Banshee needs. After the command finishes, reboot your system. After your computer finishes rebooting, you can launch Banshee 2.0 by going to the Applications menu, to Sound & Video, and clicking on the Banshee icon.
