He aprovechado el puente para reinstalar el equipo de casa y ponerle Ubuntu 14.04 desde 0 ya que quiero probar Unity después de la mala impresión que me dio hace unos años. El caso es que al instalar Dropbox, me he encontrado con que me falta el icono de Dropbox en Unity, lo que hace poco intuitivo saber cuanto va a tardar una sincronización, sobre todo la inicial.

¿Como recuperar el icono de Dropbox en Unity?

Debemos instalar libappindicator1

Como ves, el icono de Dropbox vuelve a estar en el sitio habitual.

icono de dropbox en ubuntu

He visto algunas soluciones que sugerían instalar un plugin de nautilus, pero en mi experiencia, no ha funcionado, ya que intentaba desinstalar Dropbox, y no es lo que queremos.

javi@casa:~/Downloads$ sudo apt-get install nautilus-dropbox
