Package: systemd
Version: 254~rc1-2
Affects: pbuilder
Dear maintainers,
Yesterday I tried to build a package with pbuilder and it resulted in an
error when trying to satisfy build dependencies:
Referenced but unset environment variable evaluates to an empty string:
Version
dpkg-query: error in show format: may not be empty string
/usr/lib/pbuilder/pbuilder-satisfydepends-apt checks for apt's version
with the function package_version_is_older_than, which is defined in
/usr/lib/pbuilder/pbuilder-modules:
dpkg --compare-versions "$($CHROOTEXEC dpkg-query -W
--showformat='${Version}' "$1")" lt "$2"
CHROOTEXEC is defined in /usr/lib/pbuilder/pbuilder-checkparams:
CHROOTEXEC="chroot $BUILDPLACE "
And then (if systemd is running and its version is greater than 215) :
systemctl_run=(
systemd-run
--quiet
--scope
--description="pbuilder_${PBUILDER_OPERATION}${1:+_"$(basename "$1")"}"
--slice="$SYSTEMD_SLICE"
)
CHROOTEXEC="${systemctl_run[*]} $CHROOTEXEC"
So the resulting systemd-run command evaluates '${Version}' (in the
dpkg-query command) to an empty string. It shouldn't be evaluated since
it's enclosed between single quotes.
Downgrading systemd to version 253.5-1 fixes the problem.
