I am a new Linux user, and I installed Ubuntu from scratch yesterday for the first time. I am dual booting Ubuntu and Windows 10, so following these instructions, I partitioned my drive to leave ~100GB for Ubuntu, with 10GB as root, 5GB as swap and 80GB as home.
I was installing packages, and went to install TeXlive (it's around 3.5GB). I got an error saying I'd run out of disk space. Sure enough, I open Disk Usage Analyser and the
/ directory (is this called root?) is using up 9.8 GB. Quick googling informs me this is where packages are stored. If that's the case, then I'm not surprised it's using up all of its space - if I intend to continue to install packages, do I need to enlarge it in some way?
If I do need to change the sizes of my partition, is this likely to be dangerous? The first time I tried to resize my partitions I made a mistake and had to format the whole drive to start from scratch, so I'd prefer not to mess around with that until I have some more experience, unless I really have to.
Finally, if it really is the case that I need to wipe everything and start again, please say so (the installation is still quite clean so I won't lose anything more than the time I've spent on this one). But please also tell me how to avoid making this mistake in the future!
