Failed to create swap partition by disk utility and gparted

[BertN45]

I have tried to create a 2 GB swap partition on a GPT disk using both the gnome-disk-utility and gparted.
My system is a Virtualbox VM with the standard vdi file, that I did grow in Virtualbox with 2 GB using the virtual media manager menu. It has been impossible to create any partition in that 2 GB free space using those utilities. Both first promoted to extend the last partition and when I refused and used Apply for the new partition, they both did give the notorious partitioning error message and nothing changed on the disk.

In the end I added the virtual disk to a Windows 10 VM and I used Windows 10 to create a NTFS partition in that free space. After reloading Xubuntu I used gparted to format the partition to a Linux swap partition and that is what I use now after editing fstab.
