After becoming familiar with Rasbian and Terminal, I decided to try something new with ubuntu MATE. Aside from the microSD card that the Raspberry pi came with, which I want to keep the Rasbian operating system loaded on, I have an 8 gig microSD card at my disposal. I wrote the image to the card, and I have it up and running with no issues.
Here's where the trouble starts. I have used my pi for a few days, and I have started getting low memory warnings. I only have around 400 megabytes of free storage left. I have tried resizing the file system and removing unneeded packages, but my question doesn't concern the means of making free space.
Is eight gigabytes enough to support ubuntu MATE?
Do I need more? 16? 32? 64?
