Problem

1. linux-pkg build-package jobs using 24.04 DE-based buildservers fail with:

14:24:10  Running: dpkg-buildpackage -b -us -uc
14:24:10  dpkg-buildpackage: error: fakeroot not found, either install the fakeroot
14:24:10  package, specify a command with the -r option, or run this as root
14:24:10  Error: failed command 'dpkg-buildpackage -b -us -uc'

2. After fixing 1, they failed while archiving artifacts:

16:32:29  + aws s3 sync --delete --only-show-errors . s3://snapshot-de-images/builds/jenkins-ops/linux-pkg/os-upgrade/build-package/make-jpkg/post-push/115
