At least I decided to exploit Insync to use my Google space online, I haven’t done it before because there wasn’t a gnome shell extension, that is now provided, but it lacks of instructions and on other website I follow they are very general, so this morning I spent half an hour for something that takes only 5 minutes, that’s what you should do to make it works and to make the extension to appear on the right and to work properly.
1. First of all download the main package from their website, this is the download page: https://forums.insynchq.com/discussion/1478/insync-for-linux-beta-8-0-9-23, or whether you prefer it this is the direct link: http://s.insynchq.com/builds/insync-beta-gnome-cinnamon-common_0.9.23_i386.deb, this is the version for 32 bit machine, and I know they write that is the version for LinuxMint and Fedora but works on Ubuntu too; if you need the 64 bit version click here.
3. Search for the Gnome Tweak Tool on the applications, and then switch on the button on Insync, it should appear on the right near the weather extension or so
4. (optional) I was running the extension called: “Places Status Indicator by gcampax “, it’s just a shortcut for some folders on your pc, but it sopped to work when I switched on the Insync one, anyway I started using the “All-in-one Places by jofer” and the problem was solved, and to be honest the latter extension is far better than the older one. So if you have the same problem just change extension.
