If you're interested in finding out what caused this problem, maybe look in:
/var/log/apt/history.log* and there should be a record of what command uninstalled that package. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1869857 Title: [Intel 7265][Regression] Ultimate Ears BOOM speaker disconnects immediately after pairing Status in bluez package in Ubuntu: Invalid Bug description: Laptop: Dell Inspiron 7370 CID: 201704-25503 Ubuntu version: 20.04 daily Linux kernel: 5.4.0-18-generic Bluez: 5.53-0ubuntu2 Summary ======= BT earphones/speaker cannot be connected either using GNOME control center, either using bluetoothctl. I've tried with previous versions of the kernel as well (5.4.0-14, 5.4.0-9) and it exhibits the same issue, so I believe this is a problem with bluez. However, the same procedure works fine on Ubuntu 19.10 (kernel 5.3.0-18, bluez 5.50), so I think it's a regression in bluez. Steps to reproduce ================== 1. Open GNOME control center, go to Bluetooth, make sure it's turned on 2. Put the BT device in pairing mode (usually, long press on the Power button) -> in g-c-c, the device appears as "Not Set Up" (OK) 3. Click on the device to pair it -> the device is briefly marked as "Connected", then immediately switches to "Disconnected" (Not OK) The attached btmon logs (5.4.0-18-btmon-speaker.log) show what happens when I follow steps 1-3 above. I tried the same procedure on a 19.10 live usb (kernel 5.3.0-18, bluez 5.50) and it works fine (see attached logs 5.3.0-18-btmon-speaker.log) Back to Ubuntu 20.04, if I try to pair and connect the device using bluetoothctl, it fails: $ sudo bluetoothctl Agent registered [CHG] Controller C8:21:58:B7:2E:82 Pairable: yes [bluetooth]# power on Changing power on succeeded [bluetooth]# pairable on Changing pairable on succeeded [bluetooth]# scan on Discovery started [CHG] Controller C8:21:58:B7:2E:82 Discovering: yes [NEW] Device 88:C6:26:1A:9E:AF UE BOOM [CHG] Device 61:E5:46:38:58:8B RSSI: -86 [CHG] Device 61:E5:46:38:58:8B ManufacturerData Key: 0x004c [CHG] Device 61:E5:46:38:58:8B ManufacturerData Value: 0c 0e 08 c5 ea 55 99 d4 da 92 56 98 49 f3 8b 13 .....U....V.I...
