I had run "sudo apt install qemu qemu-kvm libvirt-clients libvirt-daemon-system bridge-utils virt-manager", when this system problem detected error came. Please check it if it causes any issue.

Status changed to 'Confirmed' because the bug affects multiple users.

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.

I have no idea why lvm2 fails to install/upgrade though...
