By "solves it" I mean "the system provides a tool that automatically upgrades all your packages to (1) their most recent versions without (2) breaking anything"

By "solves it" I mean "the system provides a tool that automatically upgrades all your packages to (1) their most recent versions without (2) breaking anything". Go get, without the -u, doesn't provide (1), since it only updates to minimum versions. Go get -u doesn't reliably provide (2), since there is no way to specify incompatibilities.
