[PLUG] Ubuntu Snap?

[Denis Heidtmann]

I use ubuntu 16.04 on my laptop.  No mention of snap.  Setting up a new
desktop I started with 16.04.3.  On trying to install Gimp I get a screen
which wants a sign-up to install snap.  My web searching tells me that this
is to allow updated programs to be installed on not-so-updated OS.  The
downside is that it uses more disk space and sometimes more ram because the
dependencies are duplicated for each application.  No information
quantifying this increase space demand.

One commenter said he would use snap when he was sure there were no issues
and he felt the advantages were worth it to him.  But also no comment on
how to NOT use snap.  I saw no way to install Gimp without creating an
account with Ubuntu.  (This account-creation makes me leery.)

Opinions, suggestions?
