Public bug reported:
If this report is a duplicate it is because my first attempt resulted in
a time-out error.
Ubuntu 18.04, with latest updates.
On 20th December I did my weekly disk image as part of my back-up (BU) routine.
At that time BlueTooth (BT) was working correctly.
I completed the BU, rebooted and once I was signed in again the Software
Updater showed updates to be installed, which included KERNEL DRIVERS. On
completion of the update BT no longer functioned, with an error message like
Daemon Bluez not started. (i can't be sure exactly of the text).
I hunted for fixes on-line by removing and re-installing the BT packages, even
using a different version of the Bluez package, subscripted :i386. I did
realise from the queries on-line that this area of Linux has proved difficult
for many over the years, but for me this is the first difficulty I have had.
In summary, Restoring the most recent BU image gave me back BT, but the
Software Updater tried repeatedly to install the new kernel drivers, even when
the box was unticked. So I have uninstalled Software Updater and will rely upon
a manual update periodically until the kernel drivers problem is resolved. It's
just that I haven't worked out how to filter out the kernel updates anyway!
That's all I can give you for now, regards, Steve.
