Package: ddd Version: 1:3.3.8-1 Severity: normal One can do $ info ddd but not $ info m ddd RET or even / ddd RET Maybe your script lacks something: $ grep install-info /var/lib/dpkg/info/ddd.*ins* $ grep install-info /var/lib/dpkg/info/bogosort.*ins* install-info --quiet --section "Miscellaneous" ... Or probably install-docs should also do install-info too one day...
