I'm trying to setup a raspberry pi 3 for linux use, and I'm running into trouble with partitions. I'm very new to linux use and disk management so this is probably my misunderstanding.
I don't have enough space, by my interpretation, to use more disk space but fdisk -l shows that it recognizes the available space on the SD card: https://i.imgur.com/SwVdtEQ.png
but my filesystem can't make use of this space: https://i.imgur.com/GUu1Hte.png
How do I allow it to use the remaining ~29GB?
