Maybe rmadison (devscripts) would help you?

For example:

---------
[dragan@trios-eudev][~/Desktop]$ rmadison -u ubuntu -a amd64 libsystemd0
  libsystemd0 | 219-7ubuntu3  | vivid           | amd64
  libsystemd0 | 219-7ubuntu6  | vivid-updates   | amd64
  libsystemd0 | 229-4ubuntu4  | xenial          | amd64
  libsystemd0 | 229-4ubuntu10 | xenial-security | amd64
  libsystemd0 | 229-4ubuntu17 | xenial-updates  | amd64
  libsystemd0 | 231-9git1     | yakkety         | amd64
  libsystemd0 | 231-9ubuntu4  | yakkety-updates | amd64
  libsystemd0 | 232-21ubuntu2 | zesty           | amd64
  libsystemd0 | 232-21ubuntu3 | zesty-updates   | amd64
  libsystemd0 | 232-21ubuntu4 | zesty-proposed  | amd64
  libsystemd0 | 233-6ubuntu3  | artful          | amd64
