I am using Ubuntu MATE 16.04.1. I wanted to use BleachBit.
First, I ran BleachBit and clicked on "Preview".
It showed 556 MB cache, and I wanted to delete it, but when I tried it, the program said, that I need root permissions.
When I start BleachBit with root Permissions and click on "Preview", it says the Cache is 0 Byte.
My Hard Disk isn't that big, so 556 MB are very much for my Hard Disk.
Could Somebody help me?
