no suficiente espacio disco

Thank you for taking the time to report this issue and helping to make Ubuntu better. Examining the information you have given us, this does not appear to be a bug report so we are closing it and converting it to a question in the support tracker. We appreciate the difficulties you are facing, but it would make more sense to raise problems you are having in the support tracker at https://answers.launchpad.net/ubuntu if you are uncertain if they are bugs. For help on reporting bugs, see https://help.ubuntu.com/community/ReportingBugs .

All the downloaded updates are stored in /var/cache/apt/archives/

You can remove them all with (using terminal):
sudo rm *

Or even better, execute in terminal (autoclean - Erase old downloaded archive files):
sudo apt-get autoclean

If you execute:
sudo apt-get autoremove
It Removes automatically all unused packages

Check if this releases some space in your disk
