I fixed this by running: sudo apt purge lvm2
sudo apt install lvm2 But I wasn't using LVM and had no volumes set, so it wasn't risky for me. By the way, you could have run: sudo apt install virt-manager all the other packets you have expressly typed, with the exception of bridge-utils, are dependencies or recommends, and will get installed no matter what all those YouTube tutorials say.
