Just did a fresh install of 20.04 as a Proxmox VM and see this "invalid argument" in the start up messages and syslog. Trying to start it manually also fails. Tried recreating it, also failed.

Steps to reproduce: 1) sudo bash 2) dd if=/dev/zero of=/swapfile bs=1024 count=524288 3) mkswap /swapfile 4) chown root:root /swapfile 5) chmod 0600 /swapfile 6) swapon /swapfile Last execution returns "swapon failed: invalid argument" .
