Dropbox is a great tool for everyone, but Debian users are a bit on the unlucky side. The .deb file is intended for Ubuntu systems, so an unmet dependency pops up when trying to install it on Debian and leaves the user Dropbox-less.
One method is to compile it from source. Meh.
To install on my Debian Squeeze netbook, I followed this lazy method:
- downloaded a version of nautilus-dropbox package that is specifically built for Debian Squeeze (hats off to Elric).
- installed as intended. Dropbox is now running on my system, but it's version 0.6.3 - functioning but a bit old.
- followed the simple instructions on the Dropbox support forum to update the Dropbox installation.
Enjoy responsibly :)
