I had found a strange issue related to the package management when running a live version from a USB Stick.
When removing instaled packages, the "free space", instead of increasing (as it's wrote in the status: "XXX will be freed) decreases and it comes to the point that when I attempt to remove future packages, it get interrupted with an error of "no space left on device", even removing earlier packages with size over 70 MB.
Any ideas to solve it ?
