Bug and possible solution: actually I found a bug in that make the headset unusable, it seems that the pulse audio module: module-bluetooth-discover works only if started after the X11 session is up. So I have a workaround.
Edit the file:
/etc/pulse/default.pa
and comment out (with an # at the beginning of the line) the following line:
#load-module module-bluetooth-discover
now edit the file:
/usr/bin/start-pulseaudio-x11
and after the lines:
if [ x”$SESSION_MANAGER” != x ] ; then
/usr/bin/pactl load-module module-x11-xsmp “display=$DISPLAY session_manager=$SESSION_MANAGER” > /dev/null
fi
add the following line:
/usr/bin/pactl load-module module-bluetooth-discover
This way the Pulse audio’s Bluetooth modules will not be downloaded at boot time but after x11 is started.

Thank you for sharing! After hours of trying different things this is what got my Bose QuietComfort 35 II to connect to my pop!OS 20.04 (based on Ubuntu 20.04).

@janhohner were you what else did you try? I am still not able to connect my Bose QC35.

Thank you so much! I was having trouble connecting my Sony Bluetooth headphones to my Ubuntu system (20.04.1 LTS). I was getting the same error you described. This fixed it, and probably saved me hours of trying different fixes.
