Errno 28 No space availble on '/var/tmp/...'

Question

I would like to install algobox for my studies but it is impossible for me to install it or even to update my computer. I looked for it and I saw that it was probably a problem of space in my partition.

I made the command "df -h" to see what was in my score and it displayed this:

Answer 1

The /var/tmp does not seem to be mounted separate from / and it looks you still have 3G free

I would suggest running a "df -i" to see the inode utilization at the IUse% column(it must be under 100%) as if you have a lot of small files, each one will utilize one inode and if you are using 100% of inodes you will get the "No space left error".
