This is likely inaccurate information.
What output returns when you run:
lsblk /dev/sda?
First requirement for a new partition is available space.
I have the following output:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 931.5G 0 disk
├─sda1 8:1 0 922.7G 0 part /
└─sda2 8:2 0 8.8G 0 part [SWAP]
I have 770.83 GB free memory
