#
# After the package was installed:
# <postinst> configure <old-version>
#
#
# If prerm fails during upgrade or fails on failed upgrade:
# <old-postinst> abort-upgrade <new-version>
#
# If prerm fails during removal:
# <old-postinst> abort-remove
#
# If prerm fails during deconfiguration of a package:
# <postinst> abort-deconfigure in-favour <new-package> <version>
# removing <old-package> <version>
#
# If prerm fails during replacement due to conflict:
# <postinst> abort-remove in-favour <new-package> <version>
