Debian doesn't include license information in the package information that it provides, so apt and aptitude cannot include this metadata. This is probably because many packages contain a mix of different licenses or licenses without a well-defined short name and it is simply impossible to include such information in the package metadata. Also, it would probably fall out of sync with the copyright file, which must be included in every package anyway.
If you really want this nevertheless, please reassign this bug to ftp.debian.org, since it is not implementable in apt or aptitude. -- brian m. carlson / brian with sandals: Houston, Texas, US +1 832 623 2791 | http://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: RSA v4 4096b: 88AC E9B2 9196 305B A994 7552 F1BA 225C 0223 B187
