I can confirm we are hitting this issue when upgrading from Lunar to Mantic.

To reproduce it, one just need to launch a LXD Lunar VM and upgrade to Mantic. The process will stuck many times and will take longer than it should.

The problem seems to be that the user "usbmux" doesn't exist in the system, so whatever is trying to use it will go to systemd after looking for it in /etc/passwd.

The workaround is to add the user: useradd -u 111 -g 46 usbmux

But the real problem still must be addressed in Netplan.
