Install Dropbox in Ubuntu

Dropbox is a Web-based file hosting service operated by Dropbox, Inc. that uses cloud storage to enable users to store and share files and folders with others across the Internet using file synchronization. Dropbox provides 2 GB of free online storage. Users who refer Dropbox to others can gain up to 8 GB of additional free storage.

For installing Dropbox, download it from here:

     Ubuntu (.deb)       32-bit            64-bit 

For installing the .deb file, simply double-click on it and then select Install Package.

Alternatively, you can also install a .deb file by opening terminal and typing:

$ sudo dpkg -i package_file.deb
