To support tools (e.g. Aptly) that require Debian packages to include their MD5 checksum in their Packages metadata file for validation, you can configure Artifactory to add this value by setting the following system property in the artifactory.system.properties file:
## Add package MD5 checksum to Debian Packages file #artifactory.debian.metadata.calculateMd5InPackagesFiles=true
Artifactory needs to be restarted for this change to take effect.
