This works and updates your ssh version, but it breaks all these packages in apt, so you won't be able to use apt to install anything else afterwards.

+1 Exactly

why yould you break your installation if the whole point of having installed a distribution is to avoid custom installs. better build from sources and install under /usr/local/bin

This broke all the packages in apt and now I can't run krb5-user :( Somehow I can't manage to uninstall v7.4 and it exists simultaneously with 7.2
