Sometimes, the Ubuntu Software Center doesn’t have the most up-to-date version of a particular software.
I encountered this the other day with Dropbox and Ubuntu 14.04.
While trying to switch accounts on my old installation of Dropbox, I got a message that I had an older version of Dropbox and needed to upgrade. When I checked the Ubuntu Software Center, the latest version of the Dropbox still wasn’t there.
In this case, you can always download the latest version of Dropbox by going here.
Alternatively (this method is easier), I recommend that you install Dropbox via the command line. The Dropbox daemon works fine on all 32-bit and 64-bit Linux servers. To install, run the following command in your Linux terminal.
1) Open Terminal
2) For 32-bit, type the following:
$ cd ~ && wget -O – “https://www.dropbox.com/download?plat=lnx.x86” | tar xzf –
3) For 64-bit, type the following:
$ cd ~ && wget -O – “https://www.dropbox.com/download?plat=lnx.x86_64” | tar xzf –
4) Run the Dropbox daemon from the newly created .dropbox-dist folder by typing the following:
$ ~/.dropbox-dist/dropboxd
