PS:

"IMPORTANT NOTE

The guest session feature is available in Ubuntu 14.04 and 16.04,
including those flavors which use the LightDM display manager.

In later versions of standard Ubuntu, the feature is not available,
since LightDM has been replaced with GDM. As regards later versions of
flavors which use LightDM, the guest session feature is available but
disabled by default. As explained at this Ask Ubuntu page, guest
session can be enabled, but there is currently a security issue which
you must consider before enabling it. This bug report tracks possible
progress for that issue." -
