After further investigation I do agree that this is NOT an Synaptic issue. However, your view about the cause is wrong I fear.
I do run Gnome 3.26 already. I have a machine that is set up identically and synaptic works fine there. I currently investigate why I cannot su root and call xhost even though access rights are set correctly. Thanks for the hint though. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1717536 Title: Synaptic does not start To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/synaptic/+bug/1717536/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
