Could not install with only 2GiB of RAM

I remember something about Calamares and RAM

A very old issue on github

And that issue is referenced by a newer issue feb. 2022

sudo -E calamares -d &

I thnk the underlying issue could be the lack of swap when booting from ISO combined with the necessary space needed to hold a an squashed filesystem of more than 2gb in-memory. That is somewhat impossible with 2gb ram.

Most installer images are way beyond 2gb today.

I remember the general test recommendation for virtualbox being 2vcpu and 2gb ram.

But then - at that time - we tried to keep the images at max 2gb.

I even think there is a test script which creates a vm with 2gb ram and 10gb disk.
