Contacts keeps and organize your contacts information. You can create,
edit, delete and link together pieces of information about your contacts.
Contacts aggregates the details from all your sources providing a
centralized place for managing your contacts.
Contacts will also integrate with online address books and automatically
link contacts from different online sources.
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.
Alternatively, snapd can be installed from the command line:
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.
