Authentication error when trying to install or uninstall using Ubuntu Software Center (14.04)
I was faced with the same problem and the following solution fixed my case:
check whether you have
policykit-1-gnome
installed. (I only had policykit-1 installed before). If not, install it using apt-get.run
/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1
. Now try to start software center from launcher and software should be able to be installed successfully.add
/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1
to your startup applications. press super key and search "startup applications" in all programs. Open it and click "add" to add this command line.
Good luck.

when trying to install or uninstall from Ubuntu Software Center (14.04). I'm getting the error message
**Software can't be installed or removed because the authentication service is not available. (org.freedesktop.PolicyKit.Error.Failed: ('system-bus-name', {'name': ':1.85'}): org.debian.apt.install-or-remove-packages**
when I try to install or uninstall anything from the Center.
I'm running this through Crouton on a Chromebook. Is there anything I can do to fix this issue?
