As shown in above image /dev/nvme0n1p8 has 27 GB items, How can I see those items in my disk and can remove them so that I can have enough space ?

Answer 1

As it is full, you may be not able to add a tool to monitor your disk usage, like ncdu

• However, some directories can be cleaned easily :

  check files you need or not

  /tmp
  /var/log/
  

• Snaps are size consuming too, it holds multiple versions of the same package (rollback feature):

Check files before deleting
