>You don't really need to enable jammy-proposed. Just download the 3 proposed packages:
I first tried to install these 3 packages, albeit not with the suggested method of installing them all at once as a bundle with the dpkg command proposed by Daniel, and I ended up with a broken desktop (was getting some “Failed to start VirtualBox Linux kernel module…” errors on boot), which I fixed running sudo apt install --reinstall ubuntu-gnome- desktop). Enabling jammy-proposed seems to have fixed the issue though. Thanks!
