I've been using Linux Mint for the past week and haven't been able to launch the Synaptic Package Manager directly from the Menu (no window starts up). When executing the command
$ sudo synapticusing the CLI, the package manager window loads up and is functional, but CLI prompts me with the following error:
(synaptic:9582): Gtk-CRITICAL **: gtk_widget_hide: assertion 'GTK_IS_WIDGET (widget)' failed
Looking through the forums, I read through a few related posts but couldn't find any viable solution that took care of this.
A few things I already tried/checked on: I reinstalled Synaptic, updated/upgraded/cleaned all applications and dist-upgraded using apt, made sure my user was part of the 'sudo' group, and restarted my laptop. I also created a temporary new user to see if this issue was isolated with my user profile, but I had the same issue with the temporary user as well.
I'm not sure of any relevance here, but I did notice that I can't launch ANY of the Administration applications from the System Systems window either. From my extremely limited experience with Linux Mint, I can see that the issues have one thing in common, which is they are Administration related functions, but that is as far as my knowledge goes! I would greatly appreciate any feedback/possible solutions to this error - thank you!
