There is no way to automatically know which manually installed package should be removed or upgraded when they are not from an official ubuntu repository. This version of perl has maybe been pulled by dependency on another package. Anyhow from the system signature ( DistroRelease: Debian GNU/Linux 7) this system is clearly not a native Ubuntu system but a mix of Debian and Ubuntu which is not supported.
