As this is reported on 16.10, 2 releases before Wayland became the default window system, I wonder if this really has anything to do with Wayland. I see it mentioned in the tags but not in the bug description.
If it does have something to do with Wayland, it should be marked a duplicate of bug #1551951, which will go to the Synaptic maintainers, not as a duplicate of bug #1712089 which is a general "root graphical apps don't work on Wayland" issue. The latter will, I expect, be WONTFIXed as this is a Wayland design decision. ** This bug is no longer a duplicate of bug 1712089 Invalid MIT-MAGIC-COOKIE-1 keyUnable to init server: Could not connect: Connection refused -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1647144 Title: synaptic memory exception upon invocation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/synaptic/+bug/1647144/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
