Thank you for reporting this bug to Ubuntu.

See this document for currently supported Ubuntu releases:

We appreciate that this bug may be old and you might not be interested
in discussing it any more.
Just in case this could help when I try to manually get information on
the calibration device using colormgr I get the following error:
txelu@txelu-acer:~$ sudo colormgr get-sensors
Object Path:/org/freedesktop/ColorManager/sensors/i1_pro
(colormgr:3025): Cd-WARNING **: Failed to lock
Status changed to 'Confirmed' because the bug affects multiple users.
** Changed in: gnome-control-center (Ubuntu)
Status: New = Confirmed
