I have a brand new System76 laptop w/15.04, 250G SSD as root partition. I was playing around with pycharm, doing a tutorial when i get a pop-up saying no disk space remaining. I close out of pycharm and open file manager, sure enough, my ssd is full. I've rebooted, but still have my root part full.

How do i find out whats filling it up and clear it out??

UPDATE: I used a 'du -k / | sort -n' to find the largest files being used on the disk, then deleted them.

  • You can remove: 1) Older or unused kernels (they use quite a few space); 2) Unused programs; 3) You could clear your home folder; 4) Always use Ctrl+H in your file manager to show hidden directories/folders. May 11, 2015 at 16:11
  • this is a brand new machine, no older kernels, very few programs installed, home folder is practically empty...

  • Try opening GParted, take a screenshot and post it here. May 11, 2015 at 16:17
  • don't have gparted installed, and cant install it. (tried apt-get install gparted, got: "The package lists or status file could not be parsed or opened"

You could use baobab, a disk usage analyzer. It is installed by default

It will help you troubleshoot your problem.


  • My God, Magnum. I needed this name to be able to use it with sudo. Thanks much.

try sudo apt-get autoclean to remove the apt cache. It will give you some more space.

  • it freed 1.5GB in my machine!
