Bluetooth turns off automatically Ubuntu 18.04 LTS

[SpiderQED]

Whenever I start up my laptop and connect my JBL-speaker, the device stays connected. However, when I turn de speaker off, and try to reconnect to the speaker, the Bluetooth automatically turns off. I then need to restart my laptop and then only Bluetooth works again.

Are you able to turn Bluetooth on again using:
  Settings > Bluetooth > (titlebar) = ON
?

It sounds like bug 1595695 is one of the problems.

The other issue with auto-disabling of Bluetooth may be related to bug 1302777 or bug 1688143.

Please also run 'apport-collect 1774640' to send us more system information.

I am able to turn Bluetooth on, but after a few seconds it turns off automatically again. Only after a reboot of my laptop I am able turn Bluetooth on without any problems. I've run 'apport-collect 1774640'.

Status changed to 'Confirmed' because the bug affects multiple users.

[Matija Bertović (erinon)]

The same happens to me. After some time it automatically turns off and is unable to turn back on. The button in Bluetooth settings does nothing. I am using Ubuntu 20.04 on Acer Aspire E5-552G-T21P.

[Simon P. (simpre)]

I can confirm this problem for Ubuntu 20.04 and 20.10 on a Thinkpad X260.

The bluetooth button in the Bluetooth settings does nothing after it is automatically turned off. However, I can enable Bluetooth again by turning it off and on again Bluetooth in the menu top bar.
