You can use Snap in a VPS on vpsAdminOS. It needs the snapd service and access to FUSE. New VPSes have FUSE enabled and are ready for Snap; you only need to install the distribution packages.

See the current Snap documentation for Ubuntu for supported releases. If the snap command is not installed yet, install snapd:

apt update
apt install snapd

On a system with systemd, make sure its socket is running and wait for initial setup to finish:

systemctl enable --now snapd.socket
snap wait system seed.loaded

For another distribution, follow the current Snap installation guide. Package names and service setup may differ.

Verify the installation with a simple snap:

snap install hello-world
snap run hello-world

Inspect the system state and service messages with:

snap version
snap debug sandbox-features
systemctl status snapd --no-pager
journalctl -u snapd -n 100 --no-pager

Individual snaps may require additional privileges or features that are not available inside a container VPS. A working hello-world therefore does not guarantee that every application will work.

If a VPS does not have the /dev/fuse device, check its configuration:

test -c /dev/fuse && echo "FUSE is available"

Enable FUSE in the Features form in the VPS details. It is enabled by default on newly created VPSes. Changing a VPS feature restarts the VPS automatically; wait for it to start again, then repeat the test.

If Snap still fails, send support the VPS ID, snap name and relevant output from journalctl -u snapd.
