It seems that the version of qemu-img Ubuntu 18.04 comes with requires the disk size passed in with the postfix of 'M' instead of 'MB'.

E.g.:

if stdout, stderr, err := cmdOutErr("qemu-img", "resize", d.diskPath(), fmt.Sprintf("+%dM", size)); err != nil {

Right, it seemed to be ignored even on 16:04

   size
       is the disk image size in bytes. Optional suffixes "k" or "K" (kilobyte, 1024) "M" (megabyte, 1024k) and "G" (gigabyte, 1024M) and T (terabyte, 1024G)
       are supported.  "b" is ignored.
