I am trying to install a specific version v1.7.3 of geth using
sudo add-apt-repository ppa:ethereum/ethereum
sudo apt-get update
sudo apt install ethereum
This installs the latest package available (geth v1.8.2). But I want another package with same package name ethereum but different content (1.7.3+build11486+zesty)
I need the commands to install v1.7.3. I have to use it in a dockerfile.
