Ever since I created a Ubuntu One account, the top bar has had the little Ubuntu One cloud icon in it. I prefer not to have very many icons in the top bar, and since Ubuntu One is easy to access, I want to remove it. Is there any way I can do this?
If you don't want the indicator to show up, you can uninstall the
indicator-sync package, and stop the
indicator-sync-service process from running.
Note that it is a system indicator, and other applications, such as dropbox, may use it in the future to show information about sync status, and to interact with them.
Since Ubuntu One has stopped being developed, you can simply just remove it (and everything that has to do with it) with
sudo apt-get remove ubuntuone-*
That will also remove the indicator.
