sound – why can’t I install Ubuntu on my computer

I’ve just installed Ubuntu 20.04 on my 13 inch 2015 MacBook Pro. When I go to the Bluetooth section in Settings, I can see my wireless headphones listed. The headphones are in their pairing mode, but when I click it on list it never connects. I’ve tried with three different sets of Bluetooth headphones (Airpods Pro, Airpods, and Bose QC35). What should I do to get my laptop to connect to Bluetooth devices? I know that Bose QC35 headphones work because I’ve used them with my desktop running 20.04.
