Syncthing is a cross-platform peer-to-peer file synchronization client/server application written in Go. Similar to BitTorrent Sync, the tool can be used to synchronize files between computers however, unlike BitTorrent Sync, Syncthing is open source.
The tool comes with an option to update the binary to the latest version however, since we covered Syncthing back in June (check out that article for more information on Syncthing) there were almost 40 new versions released so using a PPA to automatically update the app is a must if you're a regular Syncthing user.
There's no official Syncthing PPA however, Niklas Sombert has created a unofficial PPA for Syncthing, so you can easily install / update the tool in Ubuntu 14.04 and 14.10. Note that unfortunately, Launchpad PPAs don't support ARM by default so this PPA won't work on ARM devices / Raspberry Pi.
Install Syncthing in Ubuntu 14.04/14.10 or Linux Mint 17/17.1 via PPA
To add Niklas Sombert's PPA and install Syncthing in Ubuntu 14.04/14.10 or Linux Mint 17/17.1 via PPA, use the following commands:
sudo add-apt-repository ppa:ytvwld/syncthing
sudo apt-get update
sudo apt-get install syncthingIf you're looking for a GUI, check out: Syncthing GTK: GTK3 & Python GUI For Syncthing [Ubuntu PPA]
