Not enough free space

[PsycoStea]

Hi there

I am booting from an Ubuntu 32GB flash on Minix Neo U9-H. Was pretty easy to get it up an running. I am using box config box=s912_generic_gigabit. I want to install PiHole but everytime I try and install anything I get the following error:

E: You don't have enough free space in /var/cache/apt/archives/.

I ran df -h and got the following

/dev/root is 100% used, mounted on /
/dev/sda1 is 15% used, mounted on /boot

If I try to install to eMMC, I get the same error. Can you please assist?

EDIT: I was able to use parted change the size of /dev/sda1 to the rest of my flash drive and now I can update and install apps
