Ubuntu – How to disable fetching of DEP-11 files


I noticed, In 16.04, apt-get update downloads more data. Some of the big files include DEP-11 things which I don't know much about.

I have found a Debian Wiki page https://wiki.debian.org/AppStream, which says these files YAML-formatted metadata provided for —

The metadata can for example be used by software centers like GNOME Software or KDE Discover to display a user-friendly application-centric way on the package archive.

But, I don't use these Software Centers and I don't want to fetch those huge files. How do I disable fetching of these wastes?

  • Looks like it is defined in /etc/apt/apt.conf.d/50appstream

    Can be disabled with:

    sudo mv /etc/apt/apt.conf.d/50appstream{,.disabled}

    That stopped it on mine, still visible in updates as:

    N: Ignoring file '50appstream.disable' in directory '/etc/apt/apt.conf.d/' as it has an invalid filename extension


    If you want, you can just move the file outside of that directory, it will no longer show up. No more notices. eg:sudo mv /etc/apt/apt.conf.d/50appstream /etc/apt/50appstream
