[Bug 1981247] [NEW] Bluetooth low energy connection can not be established since the recent ubuntu updates, more accurately the one from 06.07.2022. I haven't found out what is the reason. Every other Bluetooth command I used (with PyBluez) seems not to be impacted.

Release: Ubuntu 20.04.4 LTS
I'm guessing the related package might be bluez:
  Installed: 5.53-0ubuntu3.6

Before this update, I've had no issues establishing (low energy)
connection. However, after the update I'm getting a time-out and the
connection is never established.

I've explained the issue here as well:
https://askubuntu.com/questions/1418182/ubuntu-20-04lts-update-breaks-
bluetooth-connection

I don't see what might be the cause of the issue, besides knowing that
it started after the update.
