[SOLVED] Peculiar(?) disk usage

[SwatKat]

Hi
I installed Ubuntu through wubi . I don't remember the exact installation size, but it was definitely not more than 8GB. I have been download happy, and have run out of disk space. I ran the disk usage analyzer and what it shows(screenshot 1) has me puzzled. If I am not mistaken , the size of the root directory is 12.2 Gb and the used space is 13GB. But I am sure that the installation size was not more than 8GB. Now, every time I boot into Ubuntu, I get the message in screenshot 2. Could someone explain this to me please? I understand that the virtual disk can be resized using LVPM, but I want to know why I am getting the low disk space message now, and not when I exceeded 8 GB.

Your total usage is 12.2GB out of 21.1GB. Of that Windows (showing as /host) is taking up 7.9GB. It looks like you might have only created a ~4GB virtual partition using Wubi. I'd suggest expanding it using LVPM, like you say.

In the meantime, some things you can do to free up space:

• (Obviously) empty your trash
• Uninstall any unused kernels, they're over 100MB each. Search for "linux-image" in Synaptic and remove all except the one you're using.
• sudo apt-get autoclean && sudo apt-get autoremove. This will dump the package manager's cache and uninstall any obsolete packages.

So thats what it shows. sudo apt-get autoclean && sudo apt-get autoremove cleared up a lot of space. Thanks.
