packer doesn't work due to problems with ca-certificates for me.
To remedy, add the following bundles
ca-certificates-utils.sb
ca-certificates-20140325-2_cacert-20140824-1_mozilla-3.17.1-1.sb
and then run update-ca-certificates in terminal
BTW I miss the system sub menu collection of right-click menu
Maybe its a config matter to get it back
