what shold i do .thanks, guys!

Post your /etc/apt/sources.list file, and the output of $ df -h

Try the advice given here - I had that issue before and that's what worked for me.

Yes, edit /etc/apt/apt.conf and add the following line:
Increase the number until it works.

The reason you run out of cache space is that you have a screwed-up sources.list file.
