Bluetooth not working in Ubuntu 20.04

ls flag

I recently built a new desktop PC and I've been having trouble getting bluetooth working. Previously it was running, but not pairing to headphones. Occasionally it did pair but the sound was choppy, and it would not remember the device and so pairing was very inconsistent. In trying to fix it today I updated bluez and blueman and now I have a new problem; bluetooth won't start at all.

When I try to run blueman-manager, I now get the following error:

blueman-manager version 2.1.2 starting blueman-manager 11.02.18 ERROR Manager:118 on_dbus_name_appeared: Default adapter not found, trying first available. blueman-manager 11.02.18 ERROR Manager:122 on_dbus_name_appeared: No adapter(s) found, exiting

Bluetooth is definitely enabled in my BIOS. Some other commands and outputs:

$ systemctl | grep -i blue

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.
