Hey!
I have a patch to fix the RAM requirement on ubuntu (for 16.04, 18.04 and
18.10) that I pushed at https://gitlab.com/didrocks/osinfo-db/commit/67d8b0a34771b0e0aa8736cb707f8028e82c0bf3.
As this is only one commit, I have enclosed a git format patch version to
that email.
What triggered that discussion was
https://bugs.launchpad.net/ubuntu/+source/osinfo-db/+bug/1796037, which
makes the default RAM size not being able to install ubuntu. The ubuntu
desktop team decided to bump the requirement to 2Gb (which was the GNOME
Boxes fallback for those versions when the file definition wasn't included).
The minimum was changed by https://help.ubuntu.com/community/Installation/SystemRequirements?action=diff&rev2=108&rev1=107
about 1 year ago. My understanding is that the minimum is 2GiB while the
recommendation is 4GiB? (I'm unsure how to read the 4GiB mentioned in
that page ;)
Is 16.04 impacted by these changes in memory requirements though?
Yes, we can be more fine-grained, basically:
* 16.04 -> Min and recommended is 2Gb (this was bumped when our 16.04.x
maintenance image started to include snapd)
* 18.04 and onward: 2Gb min, 4Gb recommended.
However, if we bump recommended in that file to 4Gb, GNOME Boxes will
set that as a default, which we aren't really keen on (the 4Gb
recommended is a large estimate for people using a lot of tabs in their
browser, which isn't our GNOME Boxes typical usage we are targeting at).
Does it makes sense?

Thanks a lot in advance.
Cheers,
Didier

Subject: [PATCH] Bump minimal ram requirement for ubuntu to 2Gb
The ubuntu images needs 2Gb to end their installation process with
pre-seeded snap. Otherwise, the machine OOM and deadlock during install.
We weren't impacted previously as shipping an old osinfo-db version,
which didn't have the distribution specific requirements, and thus,
fallbacked to GNOME Boxes default which is 2Gb.
