Comment 12 for bug 1593407

From duplicate bug #1981881: guest session can be enabled in Xubuntu 22.04 by creating the following file: /etc/lightdm/lightdm.conf.d/40-enable-guest.conf
with the following content:

    [Seat:*]
    allow-guest=true

And rebooting. At the login screen, one can select a guest session, and this problem with snaps can be reproduced.
