[20:51] <tomreyn> i'm trying today's 22.04 canary in virtualbox: 1 GB RAM (as the download page says), 2 CPU cores, 20 MB VRAM, graphics acceleration and nested virtualization off. It takes ~ 5 minutes to boot to desktop, the very most of it is spent looking at a black graphical screen (without a cursor).
[20:53] <tomreyn> free -m shows 76 MB RAM available. I guess it would be wise to recommend more like 1,5 or 2 GB RAM for installation.
[20:54] <tomreyn> (i'm pretty sure the installation will fail this way, because anything i do on the GUI takes minutes.)
