Syntax, structure, indent and unneeded logic fixes

- Fix unset usage. - Fix some missing -e in echo where needed. - Add some echos, before running some commands. - Minor alignment fixes. - Don't use 'newgrp' upon lxd install, seems to have no effect. - Unify command output redirection formatting. - Make some multi-line commands to be in one line.
