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

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