It used to.

https://help.ubuntu.com/community/Installation/SoftwareRAID

However, I have a feeling that it was dropped at some point, many years ago now.

There used to be "standard" and "alternate" CD ISOs and the alt was
needed for things like upgrading an existing system _from CD_ as
opposed to from the running system over the internet. Sadly I believe
the alternate ISO no longer exists.

Anyway, yes, I think you might get further with the server disk -- q.v.

JOOI: why the older version, since 20.04.01 is out now?

Although saying that, the new server install has its own fancy
disk-partitioning setup and it might be problematic.

I upgraded my 18.04 laptop to 20.04 recently and it went fairly well.
It tried to show me all my calendar notifications for the last 2 years
or something in one go, and made a lot of noise and locked the desktop
trying to display thousands of notifications. I dropped to text mode,
killed a few apps, but the desktop didn't come back, so I rebooted
from a vconsole. 2nd boot was fine and both GNOME and Unity are
working fine now. (As "fine" as GNOME ever works, anyway.)
