Depending how you install Ubuntu server, it may require more RAM for 26.04 LTS
The Ubuntu system requirements have been updated (actually happened for 2025 release but most people did not notice it). Previously:
Minimum RAM: 1024 MB
Now:
Minimum RAM: 1.5 GB (ISO installs) Minimum RAM: 1 GB (cloud images)
This also implies that the cloud image and the server iso image are diverging a bit more than just the cloud image including cloud-init, but somehow now doing something different enough to warrant an extra 512MB of ram.
Also, for desktop users, minimum recommended RAM is now 6GB.
Who all is excited to buy more RAM so Ubuntu can force you to use snaps? ![]()

they FUCKING WHAT?
so nothingburger. Back to Debian 13. comfy
Ubuntu 20.04 LTS till I die.
use debian
Wow. I remember it ran fine on my 96MB OVZ in 2013 (no swap, oversold 40:1, uptime 600 days). Now 1.5GB minimum, **ck canonical.
What's that quote in @angstrom's signature again?
killing myself tomorrow if they increase it to 2GB
Only needs 512MB, nice
Edit: Or less with swap:
It's time to switch to debian
Or alpine.
We prefer Ubuntu Hardy, thanks.
Fuck SystemD

What's the approach to estimate complexity?
Is there actually a bump in requirements, or is 1 GB just looking a little tighter and tighter with each release, and they decided to bump up the recommendations a notch? Most likely, the current version of Ubuntu doesn't use that much less.
they probably made snap mandatory, that thing sucks so much resources. not only ram, also wasting disk
stopped using ubuntu few years ago found them then already getting too bloated.
Maybe we can still purge snapd from Ubuntu.
Snap is a curse.
Debian uses less RAM than Ubuntu and is faster too!
I liked Ubuntu because it already has preinstalled lots of tools for everyday operations and already has lots of libs, which you need to install in debian manually. When I switched to Ubuntu from Debian it was the same by performance, but last few years course of Ubuntu makes me sad. I started to switch my servers back to Debian.
Yeah that tracks, Ubuntu’s been slowly creeping up for a while now
