This a wayland security feature, not working with pkexec, which synaptic (and other app) is using. This will be worked on later, with the next 18.04 release.
The actual workaround is the open an x session, instead of a wayland one (ubuntu default), or follow the thread explanation below: https://ubuntuforums.org/showthread.php?t=2373238
