media-types binary package in Ubuntu Lunar s390x

 This package installs the configuration file /etc/mime.types, that lists
 standard media types (originally known as "MIME" types) and their usual file
 extension. This provides a simple way for programs to have a first guess at a
 file's content. On standard Debian desktop systems, one will also find more
 sophisticated tools, for instance provided by the "file" and "xdg-utils"
 packages.
 .
 The /etc/mime.types file is compiled by hand using mostly information provided
 by the Internet Assigned Numbers Authority (IANA).
