I am new to Ubuntu, I just use it through WSL to run Docker. I found that there is around 40GB being used and I'm trying to find out why.
I have run the following commands
df -ah
Filesystem Size Used Avail Use% Mounted on
/dev/sdc 251G 39G 200G 17% /
...
du -sh -x
du: cannot read directory '/wsllNePbo': Permission denied

3.7G /
After all of the 'permission denied' messages I ran the same command with sudo and just got
39G /
and nothing else.
How do I diagnose what is taking up the space and how do I clear it?
