Ubuntu 20.04 Major problem with bluetooth

py flag
Pietro Dalmazzo

I am super new to using Ubuntu and I do not know much about it, but in the last few days I am experiencing a major problem with Bluetooth as the command does not work at all, I tried to start it from the terminal and does not work, does not connect, I tried to reboot bluez many times but every time I start the PC appears a notification that says "Daemon Bluez not active"

I know that is a situation that occurred to many people but I was not able yet to find a working solution... Thank you for helping me

Edit, Results for:

Try shutting it off, remove power cord, then hold the power button for 30 seconds, connect power cord and boot

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.
