I tried to upgrade dropbox after having received a pop-up message in desktop from dropbox asking me to do it. I followed the instructions on the dropbox official downloading page. Dropbox can now only be accessed trought the command ~/.dropbox-dist/dropboxd
and it seems that my cpu is overused. When I restart my computer, dropbox still asks me to upgrade. I tried again but I had the same results again and adain
I currently use ubuntu 12.04 (64 bits). I tried to upgrade to 14.04, but the upgrading process is eventually blocked on downloading dropbox and nothing happens
