Smile ubuntu 12.04 Beta 2 / 10 gb only has 800Mb left

When down loading files from Ubuntu Software Center my /root keeps running out of space. I recieve a message that it only has 300 to 800 Mb left.

when checking with GParted the partitions are
allocated 9.5Gb /, used 8.64Gb
60Gb to /home and 12.05Gb
4Gb of Swap. / is
I recently loaded KDE desktop to try it and found I didn't like it so I did a removal from the terminal. Is this what is using up /?
This is a sudo removal recomended by

What should I look for that might use up the /.
I understand Unbuntu uses only 5Gb os less for /.

Read this, follow the instructions and heed the warnings. My guess is your cache is probably full after downloading KDEe and also the updates you will be getting. You may also have multiple kernels and you can use synaptic to clean them out.

Ubuntu 11.10 indicates during the installation that you need 4.4GB for the initial install. Anything you download and install after that will add to that size unless it is something you specifically install to your home partition.

Every time you install packages they are downloaded to a local cache. To clear that cache just launch
sudo apt-get clean
It also may be possible that you have a lots of dependencies installed that are not needed anymore. In that case the command
sudo apt-get autoremove
will do the job.
Warning: the autoremove option can be dangerous. In any case watch the output and check which packages the command wants to de-install before commiting the action. If you see packages that should not be removed (like your DE) stop the action.

use baobab to see what is using your disk space and you can try to force-delete big unecessary files.

I installed Debian Lenny to a 10GB root partition, with /home on another partition, about a year and half ago. After installing various software packages I use regularly, including I have to say the Xammp stack, I ran out of space on /.

My conclusion was that, even though 10GB might be well above the minimun requirements for the initial installation, it might not provide enough breathing room for a working installation under daily use with additional software installed.

I now routinely allow at least 15GB for / if I'm putting /home on another partition. I'm a big believer in breathing room.

You can probably free up some space by unistalling KDE using Synaptic package manager just do a search on your installed packages and select it for removal. You can do the same with other applications you no longer need.

Good luck to you!
