[Sugar-devel] Running Sugar Desktop on Ubuntu 18.04

[James Cameron]

Swarup and I worked through this.  It was caused by missing PolicyKit
action files, after native install of Sugar to /usr/local.  Fix was to
add symbolic links for the action files;

sudo ln -sf /usr/local/share/polkit-1/actions/org.sugar.* \
    /usr/share/polkit-1/actions/
