Since Ubuntu One is no more( :'-( ) I am using Copy . But I can't see the copy icon on my menu bar(or panel or whatever). I am sure that copy is running in the background(System monitor says so). I have libappindicator1 and libappindicator3-1. installed. Yet I don't see the icon. Any ideas?
BTW, I use Ubuntu 14.04 LTS with unity.
Copy.com will work and the indicator will show on the menu bar but the pull down is useless in 14.04. Copy does know this 'and may' fix in an upcoming release. The best you can do is download the tar file - expand it to your home folder.
You will have a copy folder - note the lower case 'C'. Then open the enclosed folder according to your system, 32 or 64 bits. There is a readme file in the folder.
For my 64 bit box I opened the x86_64 folder and double clicked the CopyAgent icon (file), then signed into my Copy account. To be double sure I opened a terminal and navigated to ~/copy/x86_64 and ran
sudo ./CopyAgent installOverlay
