I have a Digital Ocean VPS with 2GB RAM, 50GB space, and 1 vCPU. Running Ubuntu Server 20.04 LTS
Yet, I have only 16GB left. After looking into this further, I've found that my /var/lib directory is utilizing 22GB. Yet, when I look into those folders, I'm not seeing any files that appear to be taking up that amount of space.
This is running LAMP for a Wordpress install. I have two virtuals live the. /var/www directory is only taking up 6GB and I'm able to account for everything.

Any thoughts on why this is occurring and how to remediate?
