Hi Thomas,
nbd modules are shipped on all Ubuntu kernels, in the standard linux-
modules package.
I started a fresh Impish VM and it was there, and loadable:
$ find /usr/lib/modules -name nbd.ko
/usr/lib/modules/5.13.0-35-generic/kernel/drivers/block/nbd.ko
$ grep -Rin "nbd" /boot/config-5.13.0-35-generic
2563:CONFIG_BLK_DEV_NBD=m
2577:CONFIG_BLK_DEV_RNBD=y
2578:CONFIG_BLK_DEV_RNBD_CLIENT=m
2579:CONFIG_BLK_DEV_RNBD_SERVER=m
$ sudo apt-file search nbd.ko | grep generic

/lib/modules/5.13.0-40-generic/kernel/drivers/block/nbd.ko
$ sudo modprobe nbd
$ lsmod | grep nbd
nbd 53248 0
I then went on and mounted a qcow2 image to be sure, and it works fine.
Could you please elaborate on what you are trying to do, and maybe I can
help debug what isn't working?
Thanks,
Matthew

Title:
linux-generic kernels are missing nbd modules
Status in linux package in Ubuntu:
Invalid
Bug description:
linux-generic kernels are missing nbd modules.
Since these modules are not build and not found in linux-generic-extra
or other packages it is not possible to
- use nbd-devices
- it is not possible to mount *.qcow2 qemu virtual harddrives into your host
system
You can build these nbd modules yourself, but you need to compile the
kernel.
