Unison is a file-synchronization tool. It allows two replicas
of a collection of files and directories to be stored on different
hosts (or different disks on the same host), modified separately,
and then brought up to date by propagating the changes in each replica
to the other.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.

sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
