Hm. For fewer updates and a long lifecycle, I’d go with Debian Stable or Ubuntu LTS.
Debian Stable is rock-solid with releases every 2-3 years, perfect if you want minimal updates and maximum stability. It’s my top pick for critical servers where reliability matters most.
Ubuntu LTS offers a more user-friendly experience with long-term support (5+ years) and commercial backing from Canonical.
Either way, you get a dependable, low-maintenance server environment.
