problems starting gparted

I just installed gparted using the terminal to download the package by executing the command 

~$ sudo apt install gparted

   after it installed I then went to the Applications Folder and also used the Application Finder to locate and run the program from a GUI.
   After selecting the file and then clicking the launch button...... nothing happens.
   When I open the terminal and entered the command

~$ gparted-pkexec

   I was asked to enter in my user password.

 (xenial)dlwilson88@localhost:~$ gparted-pkexec
==== AUTHENTICATING FOR com.ubuntu.pkexec.gparted ===
Authentication is required to run the GParted Partition Editor
Authenticating as: dlwilson88
Password:

    Upon entering my password I then received this error message: 

polkit-agent-helper-1: error response to PolicyKit daemon: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: No session for cookie
==== AUTHENTICATION FAILED ===
]Error executing command as another user: Not authorized

This incident has been reported.
(xenial)dlwilson88@localhost:~$ 

    Does anyone have any idea why it's asking for my user password and then saying

Not authorized

    and why it won't open after clicking the launch
    button from within the Application Menu?
   This is what I get if I enter the command:

~$ sudo gparted

[sudo] password for dlwilson88:

======================
libparted : 3.2
======================

    and the program still refuses to launch??

   here is my os version:

~$ lsb_release -a

LSB Version:	core-9.20160110ubuntu0.2-amd64
Distributor ID:	Ubuntu
Description:	Ubuntu 16.04.4 LTS

Re: problems starting gparted

I believe there is an active bug report about this issue (authentication not working without a Gui agent). Make sure you have a policykit agent installed and running. For ubuntu, I believe its in the "policykit-1-gnome" package and the authentication agent is "/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1".

If it's not currently running, start it up and try again. If it works, check that it's enabled in Settings Manager > Session and Startup > Startup Applications.

     Any idea why all or most all of the files failed to download? Should I try getting a tar.gz or some version
     of a physical copy of the actual file? Or does the failed apt-get update mean there is an issue with my operating system?

Is everything okay with your network connection? Can you connect to: http://archive.ubuntu.com/ubuntu/dists/?

Re: problems starting gparted

I had a similar problem on a fresh install of Ubuntu 18.04 after installing xfce4.

The problem was evident as en error message when trying run 'Language Support' (gnome-language-selector) after install.

Error described here: https://askubuntu.com/questions/1031319 … 62#1127862

No PolicyKit Authentication Agent was installed - or at least not one that xfce seemed to recognise.

I solved the problem by installing one:

    $ sudo apt install policykit-1-gnome

That installed the package: /usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1.

It seemed to update the autostart list.

Though there is such a thing as 'xfce-polkit' and 'xfce-polkit-git', I could not see them on my machine and Debian [reports][3], in it's account of the package policykit-1-gnome, that xfce still uses the gnome polkit agent:

"This implementation was originally designed for GNOME 2, but most GNOME-based desktop environments, including GNOME 3, GNOME Flashback, and MATE, have their own built-in PolicyKit agents and no longer use this one. The remaining users of this implementation are Cinnamon, XFCE and Unity."

(https://packages.debian.org/sid/policykit-1-gnome)

It is worth noting that the terminal emulator that comes default in Ubuntu and is still default after installing xfce (gnome terminal) would not run polkit-gnome-authentication-agent-1 after install. I understand it may have been necessary, perhaps ironically, to run it an an xterm. I didn't attempt this. But all was well after restart.

Re: problems starting gparted

Bypass the whole issue and modify the file /usr/share/polkit-1/actions/com.ubuntu.pkexec.gparted.policy

      <allow_any>auth_admin</allow_any>
      <allow_inactive>auth_admin</allow_inactive>
      <allow_active>yes</allow_active>

I use no, no, yes.

Re: problems starting gparted

if i were running into issues like this where sudo seems to work, i'd do sudo -i to get a root shell and go from there.  be careful as root.  even with my 36+ years experience, i've fouled things up, before, needing a re-install.  fortunately never on a working machine or cloud instance.

and many programs expect more than just being root for many purposes.
