This bug was fixed in the package livecd-rootfs - 2.771
---------------
livecd-rootfs (2.771) kinetic; urgency=medium
[ Steve Langasek ]
* Drop support for building i386 images aside from the launchpad builder
images.
* Remove fwupd from the cloud images. LP: #1981109.
[ Michael Hudson-Doyle ]
* Fix some issues with the netboot tarballs:
- Include the signed shim (oops).
- Make the kernel path on disk and in the bootloader config match (more
oops).
- Make paths more architecture dependent as the code in grubnetXXX.efi to
probe a platform dependent path first doesn't work.
[ Alexandre Ghiti ]
* Install wpasupplicant by default as for now, most of the RISC-V boards
embed a Wifi chipset (LP: #1983008)

Bug description:
Looking at memory utilization in a pristine Ubuntu lxd container (top
-o RES), I see that ModemManager is running, which I was surprised to
see is present at all in the stock image.
Tracking this I find that fwupd depends on libmm-glib0, which in turn
Recommends: modemmanager.
Libraries in general should not recommend daemons, so it's possible
this should be fixed by libmm-glib0 dropping this Recommends. It
certainly doesn't seem to be a deliberate decision by the Server Team
to have modemmanager installed and running by default on all systems.
