I am using the awesome window manager running Debian 8. I am unable to open up the synaptic package manager when i go to the menubar using right click on the desktop > Debian>Applications>System>Package Manager>Synaptic Package Manager. I then get a prompt in the terminal for the root password, but after giving the password the terminal closes and nothing happens. Can anyone help?
On Ubuntu 16.04 LTS, on FVWM window manager, I kind of observer the same thing. When I press Alt+F1 then I go to:
XDG Menu > Gnome Applications > System Tools > Administration > Synaptic Package Manager
Then, on xterm I run
$ synaptic and I receive the following message:
On xterm, when I run
$ sudo synaptic the program starts normally without any warning/error message.
Make sure you have mate-polkit and mate-polkit-bin installed and it is autostarted.
This package eases using mate-polkit as PolicyKit-1 authentication agent on non-MATE desktop environments that don't auto-launch their own authentication agent (e.g., i3, awesome, ratpoison and alike).
Go to terminal (Ctrl+Alt+T) and type:
type in the password (if it asks) then instantly synaptic package manager should launch.
