Free up disk space on a Digital Ocean Droplet

Published on

I’ve been using Digital Ocean for a while now. For security reasons you should turn on automatic security updates on your Ubuntu Droplets. I believe it’s important to stay up to date with the latest security patches.

Unused Linux Kernels

This may cause a lot of disk space used by unused Linux Kernels. I’m using this command to clean them up when the disk space usage alarm fires.

sudo apt-get autoclean && \
sudo apt-get clean && \
sudo apt-get autoremove && \
sudo update-grub

You will the following output once or even more:

..

..

After that, check the disk usage with: df -h.
