Wrong Disk Free Space

[bagusnl]

Hi

I have Kali Linux 2018.1 installed. I was pretty stable until xfce stopped working and i've got it fixed so i can get into the desktop (yay).

But I get another issue, when i checked disk space using df, then it shows free 0%, but if you see the available and used space it shows that i still have ~200MB of space available. i started removing unneeded packages, it shows no space available. start deleting things, not really helps.

 

look at the attachment (yes i use virtual box linked to actual disk; the problem persist when i boot normally)

du -h --max-depth=1 is good for finding where all that data is being used. There's also good ol k4dirstat since you're in a gui. Be careful running du from the root dir, it'll run through /proc and throw a bunch of errors that gum up the output.

 

Try and knock a few hundred MB out and see if df shows a difference.

This is all also assuming you don't just have a full trash bin somewhere.

My guess is the issue is just that 127M left on / isn't enough for many programs. A lot of programs will use temp space while running, and 127M is nowhere near enough for many programs.

Adding onto what QXC said, if you run 

du -sh *

 in the root directory (you're root so you shouldn't get errors), it'll summarize the content size of each folder/file at that level. It's how I usually inspect disk usage

df -h is actually better command to show disk usage

df -h shows human readable, OP was using df -m for megabytes. Different, but still functional.

 

If you are talking about df vs du, the later shows disk usage, but specifically by showing file sizes. du is much more useful for hunting down disk use.

If you want free disk space du won't give you that. du will give you file/folder disk usages. Title is wrong then. OP did not want free disk space, he wanted file/folder sizes.
