Ok so this is my first every experience with Linux I'm running pop os on my raspberry pi 4 with a 8gb sd card which has the Os flashed to it and I put in a 16 gb USB drive for what I thought would be extra storage so now I've ran out of storage on my SD card and I tried to download a file and it gave me a warning saying I have less than 500mb left I went along with it anyway and it gave a error of course and I can't install anything basically how do I make it to where is just recognizes my USB drive as just more storage how do I make it to where when I install something through the terminal it just installs to the USB drive sry if this is a dumb question if anybody could help I'd really appreciate it.
