I am running Ubuntu 20.04.2 on a machine with Bluetooth adapter. Bluetooth is active an I have two devices, also active. But my bluetooth on ubuntu cannot find the devices, who cannot my adapter on the laptop either. It keeps searching devices endlessly. I ran "sudo service bluetooth status" and got this:

Please [edit] your question and add output of `lspci -knn | grep Net -A3; lsusb; dmesg | grep -i blue` terminal command.

And make sure your system is fully updated. Currently it isn't.

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.
