Package Management – Remove Recommended Packages


By mistake I forgot to add --no-install-recommends flag to my apt-get install command, is there a way to purge those recommended packages after they've been installed?

Best Answer

In addition to enzotibs answer, if you wish to avoid adding --no-install-recommends each time, you can also disable automatic installation of recommended package by setting the APT::Install-Recommends setting to 0:

umask 0022;echo 'APT::Install-Recommends "0";' | \
    sudo tee /etc/apt/apt.conf.d/00DisableInstallRecommends

The umask 0022 causes the file to be created with permissions 644, restrictive permissions breaks operations like apt-get -s ... (simulate).
