I'm new to Ubuntu and I've installed it (Ubuntu 16.04.6) on a partition of my 128GB SSD so that I have a dual boot operating system (windows 10 and Ubuntu). However I keep getting a warning message saying 'The volume "Filesystem root" has only 82 MB disk space remaining' and I don't know how to expand it. I tried expanding the partition ubuntu is installed on while in windows but it wouldn't let me add any unassigned storage onto the partition containing Ubuntu.
I was wondering increasing the partition size is possible (or if that is even the problem) or if I'm better off creating a new partition in my 1tb HDD and installing it there instead since I can probably only add a few more gb to the SSD ubuntu partition at most.
john@johnubuntu:~$ df -h

/dev/sda1 496M 69M 428M 14% /boot/efi

Any help would be very much appreciated.
