Thanks Sebastien. I already know uninstalling blueman doesn't help as I did install it exactly because I couldn't connect to the bluetooth device with gnome-control-center. I was pretty surprised to see it worked.
bluetoothctl behaves exactly like blueman-manager: does not work if gnome-control-center is open on the Bluetooth section, does work otherwise. This is the failure message: Attempting to connect to 00:22:D9:00:1A:6F Failed to connect: org.bluez.Error.Failed I'll reboot before collecting the full `journalctl -b 0` log you requested, so you'll get a cleaner log. ** Changed in: gnome-control-center (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1870356 Title: Can't connect to paired bluetooth devices via g-c-c; works with blueman To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1870356/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
