If you run into a situation where a Linux machine is running out of space, here’s a way to check what is taking up so much space and clean the server up.
sudo apt-get install ncdu
ncdu and you’ll be presented with an interface that’ll walk you through the directories taking the most space:
Troubleshooting – My Drive is 100% Full
If you’re having trouble installing the above, you likely have a full drive that cannot do anything else. Here are a few steps that may help:
First, see if there are any individual files you can delete to clear some space (such as in the user directory). If this isn’t an option, go into
/var/tmp and delete the files in there () this is not always a safe choice).
After that, run the following:
sudo apt-get clean sudo apt install byobu sudo purge-old-kernels sudo apt autoremove sudo update-grub
With this you should be able to install the above and check into what is taking up so much space.
