dpkg doesn't guarantee that /usr/bin/install-info is installed, but if you have an info-browser package installed and dpkg >= 1.15.4 then you have an info-browser that depends on install-info (due to the Breaks: in dpkg). In other words, install-info is installed if you have package installed that might use /usr/share/info/dir. If you really need install-info during the build process, you need to build-depend on it. But I would rather suggest to use "rm -f" to not fail if the dir file is not created instead... > So I consider the possibility that install-info is essential. It isn't.

Well, that dependency is transient and is added by dh_installinfo to sed. The dependency is satisfied by dpkg >= 1.15.4 so it doesn't make install-info essential at all (or at least it should not but apparently APT is not very smart in that respect). > Why does apt-get want to remove sed? Doesn't dpkg satisfy the depends? apt-get doesn't wants to remove install-info due to sed, but indeed the dep is satisfied by dpkg and hence apt-get should not complain... > However, despite install-info being "essential" I get a bug report #552677 > which is from install-info not being found by a sbuilder.

How does this dependency ensure install-info is installed if > the install-info provided by dpkg is just a wrapper to /usr/bin/install-info? install-info is only needed to create /usr/share/info/dir and the package using that file should depend on install-info. install-info must not be installed on all systems but only on systems that have an info-browser installed. > 2. dpkg bug in that it doesn't depend on install-info. > OR > 2. lintian should recommend Depends: "install-info" not "Depends: dpkg (>= > 1.15.4) | install-info", as installing > dpkg doesn't resolve the dependency on install-info. Those 2 are definitely not bugs. Cheers, -- Raphaël Hertzog -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
