Dear Maintainer,

Since the recent update, I cannot connect to my bluetooth headphones anymore.
Here's: the relevant part of journalctl:

$ sudo journalctl -f -u bluetooth

The headphones in question (Bose QC) were working fine before the update.

Dear Maintainer,

turns out that a workaround for this issue is to remove the device (i.e.
"forgetting" it in Gnome Bluetooth settings) and then re-pair it. I'm not sure
if this bug is related to the new version or just a coincidence.


Cheers,

Bastian

my bluetooth headset with bluez 5.77-1 and recent kernels:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1083183

and other users had the same issue:

https://unix.stackexchange.com/q/784717/74516

and the problem is fixed with bluez 5.79-1 (tested with the
6.11.9-amd64 kernel).

I am downgrading the severity of this issue since I cannot reproduce
this specific failure and the bug reporter was able to work around
this issue by using GNOME to forget the device and re-pair. (I don't
have Bose headphones but I do use other Bluetooth devices.)

I suspect that the bug reporter might not be able to reproduce
themselves if they reinstall the old bluez and upgrade again?

Occasionally, my Ubuntu system is unable to use Bluetooth devices.
Things work better after I either restart my computer or use the
"forget and re-pair" technique. This has been happening since well
before I installed bluez 5.79. I think Debian Testing users would be
better off with 5.79 than stuck on an older version.

Thank you,
Jeremy Bícha

I'm a Trixie user, with kernel 6.10.11(but it doesn't work also with
latest 6.11.7).
After bluez update 5.77-1 -> 5.79-1 I cannot send/receive file from my
phone.

Tried with two different adapters:
