I am a Linux noobie and have only used Mint for around six months now. While I have definitely learned a lot, I don’t have the time to always be doing crazy power user stuff and just want something that works out of the box. While I love Mint, I want to try out other decently easy to use distros as well, specifically not based on Ubuntu, so no Pop OS. Is Manjaro a possibly good distro for me to check out?
I don’t know about security updates, but what you just described in the first sentences is literally the definition of an unstable release
No, unstable just means it isn’t tested, not that people literally do not pay attention to version constraints when assembling a collection of packages.
