Dependencies issues when installing Issue Pack on Ubuntu Ubuntu 16.04 LTS (run as local server user site)

site@q:~/Issue-Packs$ npm run setup

> issue-pack@0.9.1 setup /home/site/Issue-Packs
> npm install && npm link

npm WARN deprecated node-uuid@1.4.7: use uuid module instead
npm WARN deprecated to-iso-string@0.0.2: to-iso-string has been deprecated, use @segment/to-iso-string instead.
npm WARN deprecated jade@0.26.3: Jade has been renamed to pug, please install the latest version of pug instead of jade
npm WARN deprecated minimatch@0.3.0: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
