The publisher of snap
%q has
indicated that they do not consider this revision
to be of production quality and that it is only meant for development or testing
at this point. As a consequence this snap will not refresh automatically and may
perform arbitrary system changes outside of the security sandbox snaps are
generally confined to, which may put your system at risk.
If you understand and want to proceed repeat the command including --devmode;
if instead you want to install the snap forcing it into strict confinement
repeat the command including --jailmode.
