I'm having trouble with my partitions in gparted. I have Ubuntu 16.04 (/dev/sda5) and Mint 18.1 (/dev/sda2) installed on this dual-boot laptop. I had each setup with 140.15GB of space. When I noticed that I was getting fairly low on space in Ubuntu, I decided to shrink Mint by 20Gb and grow Ubuntu by the same amount. Shrinking Mint was no problem, but now that space is just unallocated, since gparted won't allow me to grow the Ubuntu partition to use the new unallocated space. Is that because they are not adjacent? Is there a workaround?
