The home interface allows access to non-hidden files owned by the user in the user’s home ($HOME) directory where a user normally stores their personal files and documents.
The majority of snaps use strict confinement and do not have arbitrary access a system’s resources, including file and directories in the /home directory. Without this access, home will not be visible in file requesters, or as a destination from within the snap application.
To check whether a snap can connect to $HOME, use the snap connections command:
$ snap connections <snap-name>
Interface Plug Slot Notes
home <snap-name>:home - -
The above output shows that <snap-name> does provide a home interface (in the Plug column), but that it’s not connected to any slot (denoted by the - in the slot column).
Use the snap connect command to connect an interface:
$ snap connect <snap-name>:home :home
The :home slot, with no <snap-name> before the colon (:) is equivalent to directing the plug to connect to the system, which in this case is the $HOME directory.
A snap developer can request permission to have the home interface connected automatically. In this case, non-hidden files and directories will be accessible from that snap without any further configuration being necessary.
Requires snapd version 2.33+.
Interface documentation:
This is a snap interface. See Interface management and Supported interfaces for further details on how interfaces are used.
