This seems to be an issue within policykit itself. Printing the actual error shows:
GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: process with PID 12570 has been replaced >From reading the source code, it seems that policykit is checking the start time of the program and finds a mismatch. It happens that orca is run as a Python script, so I thought that might be due to the script startup procedure, but starting a C brlapi client gives the same issue. At any rate, really looks like not an issue in brltty itself. ** Package changed: brltty (Ubuntu) => policykit-1 (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782320 Title: Braille display inoperable in GUI since polkit-update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/policykit-1/+bug/1782320/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
