upgrade will work because it updates libssl1.0.0 which is the package you want upgraded :) Openssl is the command line package and libssl1.0.0 is the library. i was able to upgrade openssl without upgrading libssl1.0.0.

i wonder how many people will do apt-get update openssl and assume they have fixed it
