    Bluetooth search and pairing fails on two machines new installs of 20.04

    Overview:
    Search for device fails on two machines both with fresh installs of 20.04. One of the machines is a 2011 mac mini which previously
    had 16.04 and on that version bluetooth worked flawlessly. The other machine is a new HUNSN i5.
    The device - a wireless keyboard that pairs successfully with tablets and smartphones, and did pair successfully and work well on the
    previous version of 16.04 on the mac mini.

    Diagnostics - bear in mind that I am six years retired from web development on linux platforms and as they say - if you don't use it
    a lot, you lose it a lot.

    In addition, crashes are associated with both the use of the Control Center feature and the applet.
    Attempts to pair have made on both MATE and GNOME.
    Hopefully some of this code will edify wiser heads than I,
    and I can get my bluetooth back.
    Thanks
