ncdu (NCurses Disk Usage) is a curses-based version of the well-known 'du', and provides a fast way to see what directories are using your disk space.
After installation, run the following commands:
sudo snap connect ncdu:home
sudo snap connect ncdu:removable-media
sudo snap connect ncdu:mount-observe
sudo snap connect ncdu:system-backup
The snap version is slightly hobbled. It may not have access to all mounted drives even after applying all the snap connects.
