Status changed to 'Confirmed' because the bug affects multiple users.

[Laurent Bonnaud (laurent-bonnaud)]

According to this:

  https://raspberrypi.stackexchange.com/questions/40839/sap-error-on-bluetooth-service-status

the error messages about SAP can be avoided by starting bluetoothd with the "--noplugin=sap" option.

Since SAP is probably of little use in Ubuntu and since it does not work anyway, how about disabling it by default?

This bug still exists in zesty:

Thank you for reporting this bug to Ubuntu.
Ubuntu 17.04 (zesty) reached end-of-life on January 13, 2018.

See this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We appreciate that this bug may be old and you might not be interested in discussing it any more. But if you are then please upgrade to the latest Ubuntu version and re-test.

If you then find the bug is still present in the newer Ubuntu version, please add a comment here telling us which new version it is in and change the bug status to Confirmed.

[Laurent Bonnaud (laurent-bonnaud)]

The error messages about the sap-server are not there any longer in Ubuntu 17.10.
Thanks for the fix!

The issue still exits on Debian 9

Please help, thanks so much
