Running kernel seems to be up-to-date.

No services need to be restarted.

No containers need to be restarted.

No user sessions are running outdated binaries.

No VM guests are running outdated hypervisor (qemu) binaries on this host.
sudo: qemu-debootstrap: command not found

[Describing the problem]
mk-sbuild relies on "qemu-debootstrap" from "qemu-user-static". This binary (/usr/sbin/qemu-debootstrap) used to be available in Ubuntu <=23.04 as part of "qemu-user-static" <=7.2, but is no longer present in Ubuntu >=23.10, because "qemu-user-static" 8.0.4 doesn't have it.

[Request]
Given that if we use the Debian latest version we get:
/usr/sbin/qemu-debootstrap
W: qemu-debootstrap is deprecated. Please use regular debootstrap directly

Can you please update the code to use debootstrap instead?

Thank you!

I ran into this when I was trying to build an amd64 schroot on arm64.

I had meant to build an arm64 schroot, and once the host and schroot had the same arch my command worked.
