Synaptic packge manager doesn't work after upgrade to 18.04

[David_Partridge]

The synaptic shortcut in the menu which invokes synaptic-pkexec doesn't work after upgrading from 16.04 LTS to 18.04 LTS. I was running 16.04 LTS server with Lubuntu installed.

I can start synaptic from a root command prompt. I tried xhost +si:localhost:root from a root command line but that doesn't appear to solve the problem

I tried invoking pkexec synaptic from a command line session and got:


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


Thanks

Are you opening a wayland session ? Synaptic works on xorg session here.

[David_Partridge]

Say what I just login from the GUI prompt - I wouldn't know what Wayland was if it jumped up and bit me.

I think this is a common issue with a lot of stuff as I just tried to logout/shutdown from a X session login and got:


GDBus.Error:Org.freedesktop.DBus.Error.Interactive AuthorizationRequired: Interactive Authentication required

My default display manager is LightDM

When I login XDCMP I see the following in syslog:

which I am fairly sure is relevant to the problem.

[mc4man]

In your home folder, at bottom there should be a file called .xsession-errors, see what it says. (hidden file, if not visible go ctrl+h
Maybe also check for ownership, this should return nothing

ls -lA |grep root
You could also try deleting the .Xauthority file & rebooting.

The synaptic in wayland error is similar but different, so not that..

If I try to invoke Synaptic Package Manager through the menu, the .xsession-errors file looks like this:

Deleting .Xauthority file and force reboot didn't fix anything

Think to clean the system with: autoremove, gtkorphan & bleachbit (as root, carefully select settings)

[David_Partridge]

Did an apt-get autoremove - nothing to do (probably already did it after doing the release upgrade).

gtkorphan found a few orphans but deleting those hasn't changed anything.

The rough way: purge synaptic , then reinstall it

[David_Partridge]

Bump - does anyone have any idea about this?

[David_Partridge]

This is Bug #976638 go here: https://bugs.launchpad.net/ubuntu/+source/policykit-1/+bug/976638 and scroll to the bottom. I installed lxsession-edit and enabled "Policykit Authentication Agent". I'm sure there's a way to control this manually by editing a file, but can't work that out right now.

Everything now works OK. This needs to be fixed - as I'm sure LOADS of people migrating from 16.04 LUbuntu will be burnt by this.
