I am trying to start Bluetooth service in Ubuntu 20.04.

I have installed Bluetooth manager and it shows "bluez daemon is not not running, blueman manager cannot continue, probably means there were no Bluetooth adapters detected or Bluez daemon was not started"

I ran command in terminal and got rfkill list and there was no bluetooth listed only wireless Lan.

What do I do?

LAPTOP HP MODEL: 15da1058TU
Subsystem
             vendor: Intel Corporation

I can not find any information about Bluetooth. I think it doesn't have Bluetooth.

I ran this command in the terminal.

dmesg | grep -i blue

output:

audit: type=1107 audit(1629435095.152:91):

member="GetManagedObjects" mask="send" name="org.bluez" pid=11367
label="snap.brave.brave

Then I ran sudo lshaw -C network .

output:

What is your laptop model? Does your Bluetooth chipset appear in `lsusb`, `lspci` or `lshw`? If so, can you update the post with your Bluetooth chipset? Otherwise, can you tel us your Wi-Fi chipset?

Your Bluetooth is provided by the RTL8723DE combo wireless adapter shown in the `lshw` output. Support was added to the kernel mainline for this adapter, so it should be working. Have you tried Ubuntu 21.04, which has a newer kernel version?

No. I am using linux for first time with UBUNTU 20.04. is there any way to get bluetooth started?

Can you try booting 21.04 to see if it does resolve your issue?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
