I noticed that you launched libertine-launch on the command line, which is not supported, so I don't think this is a bug.
I think you tried to run it like: /usr/bin/python3 /usr/bin/libertine-launch wily ls which is absolutely going to cause issues. If you disagree, then we can discuss further:) ** Information type changed from Private to Public ** Changed in: libertine (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1539107 Title: libertine-launch crashed with ConnectionRefusedError in launch_application(): [Errno 111] Connection refused To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libertine/+bug/1539107/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
