Thanks for the hint, Jeff. I have now run sudo apt-get install ssmtp
and postfix got smoothly replaced by ssmtp, without lsb or any package from OpenPrinting being uninstalled. Having a look at the files contained in ssmtp with dpkg -L ssmtp shows that there is no daemon (No file in /etc/init.d/). Now the only problem is that we must make the use of ssmtp automatic, so that postfix does not get installed when a user tries to install an LSB package, especially a manufacturer-supplied printer driver. First, ssmtp needs top be moved into main, a MIR (Main Inclusion Request) needs to be posted. In addition it needs to be added to the CDs, but it is very small: t...@till-laptop:~/printing/openprinting/website$ dpkg -p ssmtp | grep -i size Installed-Size: 8 Size: 54436 t...@till-laptop:~/printing/openprinting/website$ ls -l /var/cache/apt/archives/ssmtp_2.62-3ubuntu1_amd64.deb -rw-r--r-- 1 root root 54436 2009-05-04 23:07 /var/cache/apt/archives/ssmtp_2.62-3ubuntu1_amd64.deb t...@till-laptop:~/printing/openprinting/website$ Perhaps one can even remove postfix from the desktop CDs (if it is there). As a next step a prioritization needs to be done, so that the virtual package mail-transport-agent pulls ssmtp by default. -- installing lsb requires postfix https://bugs.launchpad.net/bugs/141641 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
