Hi Thomas, hi list,
I have installed teTeX 3.0 from the distribution on a Debian system with up-to-date packges from the 'testing' branch. In this configuration, teTeX's install-info conflicts with install-info from the dpkg package. Of the latter, I have version 1.10.27 installed, but the problem may be older. Debian's install-info accepts a -description="text" option, which teTeX's does not know about. This blocks package management if the teTeX binary happens to be in root's path.
As a workaround, I have renamed the install-info symlink that I created from /usr/local/bin to the installation location.
The problem was probably introduced when updating dpkg after installing teTeX, so there is no real fix.
Greetings, Felix
