My disk space keeps dropping even when I'm not installing anything! Before I had 9.5 GB. 2 days later, it changed to 8.9, another day later 8.2, now 7.9! This is really getting me angry!
What I found interesting is it still says 9.4 in the app "Disk Usage Analyzer" but in Nautilus (File manager), it shows the memory usage. Is the space it shows in Nautilus not real and just a bug and the space is Disk Usage Analyzer the real amount storage I have left or is it the opposite? What I find weird is in Nautilus, when I click properties in the / directory, it says 21.2 used space, 30.6 total capacity. When you subtract 30.6 by 21.2, you get 9.4. That's pretty interesting. By the way, it says 7.9 / 30.6 available // when you click "Other Locations" in Nautilus.
df -h gives me
