The following is the current status of my disk:

I added sda4 as above, is there any way to increase the root capacity to sda4?
You can extend the VG and LV by commands:
pvcreate /dev/sda4
vgextend ubuntu--vg /dev/sda4
lvextend -L+4GB /dev/mapper/ubuntu--vg-ubuntu--lv
The last command add 4 GB space to /
and then extend your filesystem. It it's ext4
use command:
resize2fs /
If its XFS
you can use command
xfs_growfs -d /
Both resize commands can be done on the fly (w/o unmount the filesystem)
