No space left on device even after deleting files

I used bleachbit on root and after deleting 100s of megabytes it still says there is no space left on device? What can I do to fix this? I believe this is a bug in Ubuntu and it remains unfixed! I deleted so many things and it still is not enough space even after emptying trash can! folder . REINSTALLATION OF UBUNTU IS NOT AN OPTION

 root@ubuntu:~# df -h df: `/media/bd4729a5-5939-40c7-a1f3-62c76ec30750': No such file or directory df: `/media/B6A7-C601': No such file or directory Filesystem Size Used Avail Use% Mounted on /dev/loop0 18G 18G 0 100% / /dev/sr0 1.1G 1.1G 0 100% /media/PS2_Live_Linux /dev/sda2 62G 40G 22G 65% /media/A000B2F200B2CF12_______ gvfs-fuse-daemon 18G 18G 0 100% /root/.gvfs root@ubuntu:~# df -i df: `/media/bd4729a5-5939-40c7-a1f3-62c76ec30750': No such file or directory df: `/media/B6A7-C601': No such file or directory Filesystem Inodes IUsed IFree IUse% Mounted on /dev/loop0 1136464 535980 600484 48% / /dev/sr0 20 20 0 100% /media/PS2_Live_Linux /dev/sda2 22756808 237834 22518974 2% /media /A000B2F200B2CF12_______ gvfs-fuse-daemon 1136464 535980 600484 48% /root/.gvfs

cd /
du -h --max-depth=1

That will give you an idea of where the space is used. Go for a deeper max-depth if you want, or cd down the tree and run it again to get more info etc. It is likely that by deleting hundreds of MB all you did was free up more space to be consumed by a log file or something else. Find the source of the space usage, fix any problems that are causing the space usage etc and remove files that are using the space. At a glance bleachbits seems to focus on clearing temp files, cookies etc. I don't know that it looks through the whole directory structure.
