Yesterday, I had my main Linux partition more than 60% free.

Today, I tried to upgrade the system (as usual, each day) and it tells me: There is not enough room to perform the upgrading. Please, free 70 GB at least.

Then, I checked the partitions and... Effectively, really, the main Linux partition is almost full!

But... I didn't load (install) anything new!

I tried to free space with the following commands:

sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get clean
sudo apt-get purge
sudo dpkg -l |grep -i ^rc
sudo dpkg -l |grep -i ^rc | cut -d " " -f 3 | xargs dpkg --purge

And... NOTHING! The system doesn't free anything.

At the same time, when I type sudo -i into the Terminal session, the system tells me: 

Impossible to resolve the host 'my_user_name'

What's wrong here?

How can I fix it?

    Run the Disk Usage Analyser on your root partition which should tell you what is using all of the space and potentially what is causing this.

    Have you been manually updating kernels, and not deleting old ones? I have seen this on my machines when I forget and have too many kernels installed.

  • Where is that "Disk Usage Analyser"?

  • Either search for Disk Usage Analyser in the dash or type baobab in a terminal session.

This problem was almost auto-solved.

The problem began when a WineHQ (Windows) apps chrashes.

I think/guess/assume that some temporary hidden files used by that app, filled the partition.

I ran that app again and... "magically" the partition goes back to the original state (more than 70% empty).

The only one question still is in my mind is:

Is there a way to avoid this? ???
