Ubuntu 9.10 dubbed Karmic Koala was recently released. One of the major features was the introduction of a file sync service from Ubuntu with 2GB free space.
Dropbox has long offered support for Ubuntu Linux. And they have answered yet again by updating it for Ubuntu 9.10.
If you’d like to try Dropbox or even use it alongside the Ubuntu file sync service, here are the package repositories.
The Karmic repository is up and running and ready to add to your apt sources:
deb http://linux.dropbox.com/ubuntu karmic main
deb-src http://linux.dropbox.com/ubuntu karmic main
