Installed bluez 5.50 -> same result. Installed linux 5.3 -> same result.
Tried a combination of all the linux/bluez possibilites -> same result. Until now, I was only looking at the output of btmon (so basically, low level BT commands). Then, while I was doing one of the tests above, I tailed /var/log/syslog, and I saw this weird thing whenever I tried pairing a BT device (just when it turned from "connected" to immediately "disconnected" in g-c-c): bluetoothd[965]: a2dp-sink profile connect failed for 88:C6:26:1A:9E:AF: Protocol not available bluetoothd[965]: a2dp-source profile connect failed for 88:C6:26:1A:9E:AF: Protocol not available Turns out [1] this is because I was lacking the pulseaudio-module- bluetooth package! After installing it and restarting the device, I can pair and connect my usual BT devices... I don't know why it used to work earlier (while I was already on 20.04) and why it broke one day. I kept upgrading regularly using `sudo apt update` and `sudo apt dist-upgrade`... Anyway, it seems the issue was a non-issue... and I wasted a lot of time investigating it!
