I am having the same issue as Rob Lewis. Running Ubuntu 14.04 and a new Linux user as well. Saw the advice from Stephan which I will try, but I am having a hard time connecting all the dots between Oppa's help and Energia's install guide.
When I follow the directions from Energia's install guide, http://energia.nu/guide/guide_linux/ I am told I do not have permission to save the file. What step am I missing. I looked at Ubuntu's help forum but did not see anything specific to Energia or the Launchpad
Any help is much appreciated
