I need more space on my root partition running Ubuntu 17 (using Xfce session).
I do have a lot of unallocated space BEFORE.
However, when I try to resize root partition -
/dev/sdb2 , I can't add/remove a MiB...
Is this even possible?
If so, can it somehow be done from the live system or do I have to use live CD/USB?
There is really just Ubuntu and Xcfe session, LUBUNTU_SYSTEM is just an old label :)
