Issue with 100% /dev/root, someone help?

Hi

I am having following issue. Please see below, /dev/root is 100%

pi@raspberrypi:~$ df -h --total
Filesystem Size Used Avail Use% Mounted on
/dev/root 6.0G 5.7G 0 100% /
devtmpfs 459M 0 459M 0% /dev

tmpfs 463M 0 463M 0% /sys/fs/cgroup

/dev/mmcblk0p5 30M 398K 28M 2% /media/pi/SETTINGS
total 25G 5.7G 19G 24% -

and I am starting to see the following issue when I try to autocomplete a bash command (i.e. cd)

. cd F-bash: cannot create temp file for here-document: No space left on device

I know that issue raised is a consecuence of running out of free space in root, but how do I fix it? I have already try to expand filesystem, it does not allow me as it has been already done by NOOBS..

Any suggestions are appreciated

You can free up some space (Probably not a lot) by deleting compressed log files in /var/log. That should give you some room to go exploring what else is eating up your file system. If you don't use minecraft or mathematica/wolfram you can probably remove them.
Long term solution is get a bigger sd card and clone the current card

Thank you very much mate..I will give a go to clonning the SD card. I guess there are plenty of tutorials on how to do it...

Also run sudo apt-get clean. That will delete any old package install files left behind from any install/upgrade operations.
