I'm having the most complicated time trying to get packages to install.
I keep getting this message when trying to install them..
geth-stable no installed. the package was not found with the source(s) listed. If you specified a particular version and are receiving this message, it is possible that the package name exists but the version does not.
I am following instructions listed on the ethereum . org site but can't seem to get the packages to install with those instructions.
