I'd recommend staying on the tagged versions rather than master of so many packages, unless you're contributing to the package in question. On master you could get unstable work or unsatisfiable requirement conflicts as you saw. Most package authors are usually pretty responsive about tagging new releases for bugfixes or ready-for-public-consumption new features if you ask on github.
If you're finding a nonresponsive package author who you think may have abandoned a package, there are options for adopting on a fork and making that the new official version metadata points to.
