Help with full disk space after apt-get



I’ve been trying to install some packages on my c9 worskpace ( wich demanded some installs through apt-get.

After that, my disk space reached it’s limit and i’m unable to use any terminals to try and free some space.
I also tried removing some unused projects, but they don’t occupy much space do beggin with so it didn’t do much.

I’ve seen a couple topic here with this same problem before that manage to get it solved by the support. Any sugestions?

Thanks in advance.
