Package: apt Version: 0.1.7 Severity: wishlist It would be nice if apt-get would have the following feature:
Currently, if you call "apt-get install PKG" and PKG is already installed, apt-get tries to update the package if a newer version is available. Could there be an option --no-upgrade or the like that avoids those upgrades (but not installed packages will still be installed)? Background: I use apt-get together with my source dependency based build daemon system. apt-get does the "dirty" work of installing needed source dependencies. But if a package is listed as src dep, it will be on the apt-get install command line, and thus upgraded if not the newest version is already installed. But it happens more or less often in unstable that I do not want to use the newest version of a package for development. I'd more like to upgrade the system by hand in a controlled way. Ok, it would be possible to find out which packages are already installed and leave them out, but this is a lot of extra work and apt-get has all the infos available. It should be rather trivial to implement the --no-upgrade there. It's just the more convenient place to get the desired functionality :-) A second reason why I don't like these auto-updates is that some package do not install nicely if stdin is redirected from /dev/null. I need to do this, because the daemon who call apt-get cannot answer questions from a postinst :-) I can't avoid this if a source dependency isn't installed yet, but it's unnecessary if the package is already available, just not the newest version.
