'command blkid don't show my partitions UUID

I'm using Ubuntu. command blkid or blk /dev/sda2 in LPIC-1 module 104.3 (mounting and unmounting). but these commands don't show me the expected results. blkid is installed and also I can see man blkid !!!

Could you guide me to fix this?

Run sudo blkid
