docker - In apt-get, is there an option to assert that a package is a certain version number?

I'm running a Ubuntu-based Docker image to run a Bitcoin network in regtest mode. The docker image is in this github repo. After adding the PPA for Bitcoin, it seems that 0.15 of bitcoind installs instead of the new 0.16.2. I want to find out the source of the problem, and was wondering if there is a way to halt installation if the version number of a package doesn't match what I specify, and spit out an error if that is the case.
