not enough free space in /var/cache/apt/archives

[dukla2000]

I keep putting off asking for help, have been looking on line for a solution to the various messages of "not enough disk space in file system root.." that comes up on my phone.  I have attempted to resize when I use Jumpdrive and then the disk utility or gparted on my desktop, but one time I think I wiped the wrong partition, and then despite reading and reading, I just don't have a clear idea of how to go about increasing the root file system without wiping everything.  I have the 7-17-20 image flashed to the EMMC. I'm now unable to update due to not enough free space in /var/cache/apt/archives for the 92.6MB of archives. 
Your help would be appreciated. I apologize for asking what must seem elementary to you all....

The wiki has one way to do it. I do something similar each time I flash an image. I usually use JumpDrive and dd the image from my RockPro64, then

Code:

sudo parted /dev/sda
resizepart
2
100%
quit
sudo resize2fs /dev/sda2
