Solution 1:

You are using LVM and your logical volume is only 200GB. You can extend your logical volume with the following:

lvextend -l +100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv

You do not need to unmount to extend it. After that, extend the volume group with:

resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv

You can view status with these commands

pvs (view physical volumes)
vgs (view volume groups)
lvs (view logical volumes)

Another option would be to create more volumes and mount points using LVM, then move the data over to the new mount point. For instance make a /var volume and move the data from your /var to it, clean up the old and mount the new.
