  32         <p>The <a href="https://wiki.debian.org/DEP-11">appstream system</a> is
  33 taking shape in Debian, and one feature set that is very convenient is
  34 its ability to tell you want package to install to get a given
  35 firmware file.  This can be done using apt-file too, but that is for
  36 someone else to blog about. :)</p>
  37
  38 <p>Here is a small recipe to find the package with a given firmware
  39 file, in this example I am looking for ctfw-3.2.3.0.bin, randomly
  40 picked from the set of firmware announced using appstream in Debian
  41 unstable.  In general you would be looking for the firmware requested
  42 by the kernel during kernel module loading.  To find the package
  43 providing the example file, do like this:</p>
  44
  45 <blockquote><pre>
  46 % apt install appstream
  47 [...]
  48 % apt update
  49 [...]
  50 % appstreamcli what-provides firmware:runtime ctfw-3.2.3.0.bin | \
  51   awk '/Package:/ {print $2}'
  52 firmware-qlogic
  53 %
  54 </pre></blockquote>
  55
  56 <p>See <a href="https://wiki.debian.org/AppStream/Guidelines">the
  57 appstream wiki</a> page to learn how to embed the package metadata in
  58 a way appstream can use.</p>
  59
  60 <p>This same approach can be used to find any package supporting a
  61 given MIME type.  This is very useful when you get a file you do not
  62 know how to handle.  First find the mime type using <tt>file
  63 --mime-type</tt>, and next look up the package providing support for
  64 it.  Lets say you got an SVG file.  Its MIME type is image/svg+xml,
  65 and you can find all packages handling this type like this:</p>
  66
  67 <blockquote><pre>
  68 % apt install appstream
  69 [...]
  70 % apt update
  71 [...]
  72 % appstreamcli what-provides mimetype image/svg+xml | \
  73   awk '/Package:/ {print $2}'

  96
  97 <p>I believe the MIME types are fetched from the desktop file for
  98 packages providing appstream metadata.</p>
