Hi,
I am stuck with an error updating linux headers that I am not able to resolve. When I type in

Code:
sudo apt-get -f upgrade
Lubuntu proceeds to fetch the required packages, but then I get the following message:

In the message it says: "No space left on device". I don't get that, because when I run

Code:
df -h

...which seems to suggest that there is plenty of space for the updates.

Thanks in advance!
