I have installed parity and it runs for PoA. When I try to install geth it fails -
sudo apt-get install ethereum Reading package lists... Done Building dependency tree Reading state information... Done Package ethereum is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'ethereum' has no installation candidate
I want to use web3 functions with parity and hence I want to use geth attach. Can geth be installed with parity?
