Source: xbacklight Version: 1.2.1-1 Severity: minor This package is among the few that still use source format 1.0. Please upgrade it to source format 3.0: https://wiki.debian.org/Projects/DebSrc3.0
If you do not want to move to format 3.0, please at least specify 1.0 format so that dpkg-source can move to default 3.0 format.
