Seems to be on it's own disk. What is the output of:

sudo parted -l; lsb_release -a; uname -a

Thanks

Probably the easiest approach is deleting the swap partition (partition number 5), extending /var (partition number 4) to use the space that the swap partition was using, and then adding a new swap partition behind /boot (partition number 6)

Or you just create a new partition at the end in the desired size and use it for /var and leave the current var partition as spare for whatever other purpose.

Remark: These actions cannot be performed by the system that uses these partitions, but you have to boot from a different medium, e.g. a live DVD or USB stick in the "try Ubuntu without installing" mode.

Another item that could be worth checking: why is your /var partition too small?
Is there a process with problems that creates thousands of entries in the system log?

Can you help with this problem?
