Debian is saying that i'm out of space when ever i try to install or remove packages

Question

here's the return from df:

~$ df
Filesystem              1K-blocks     Used Available Use% Mounted on
/dev/mapper/debian-root    321041   310074         0 100% /

/dev/mapper/debian-var    2817056   577944   2076296  22% /var

as you can see debian-root is all full but debian-home has not been used at all. how can i fix this?

btw, the error that i'm getting is as follows:

~$ sudo apt-get upgrade
E: Write error - write (28: No space left on device)
E: Write error - write (28: No space left on device)
E: Write error - write (28: No space left on device)

Solution

The issue is your / (root) and /tmp folders are full and / is way way too small. You've got to delete things on /tmp and / so you have maneuvering room to do something, that something being deleting packages to give you breathing room to migrate everything to a system with sane partition sizes.

And leeduhem, moving /usr under /home will do no good. It's broken out as a partition and has plenty of free space.

/tmp folder is full as well, which you need target first to empty in fact

What does mount | grep /var show? Having separate partition with lots of free space on it which is seemingly there to hold /var does not mean it really is mounted there. Sorry for the somewhat silly comment but it's better to double check.
