I'm getting a pop up error message that my computer can not update due to low disk space on boot. I'm a bit of a newb. It seems like the thing to do is to delete old kernels, but I don't think I have old kernels to delete. Here's the output of a few commands that might be relevant to solving my problem. cat /etc/fstab # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed.

Dear Ethan, it's because /boot partition is full with 96%: /dev/sda1 236M 213M 12M 96% /boot at /boot are the kernel images saved, you can delete/purge some of the old ones (sudo apt-get purge linux-image-3.19.0-26-generic). See also here: http://askubuntu.com/questions/142926/cant-upgrade-due-to-low-disk-space-on-boot Does that help ?
Hi Schorny, Thanks, I think that solved my issue! So does that mean that out of all my kernels from 3.19.0-26 to 3.19.0-42, I could safely delete anything older than 3.19.0-42? Although I'd probably want to keep my second oldest kernel just to be safe right? I was afraid to delete any of the 3.19.0-* kernels in case they were dependant on each other. Correct me if I'm wrong, but I assume that's not the case. Thanks for helping out a newb *edit Looks like my new df -h lists boot as %60 full after removing a couple kernels, and my computer still boots. Thanks again!

Exactly I couldn't explain that better. Happy to hear its working. I'm not sure, but i guess other distributions are going to delete old kernels more quickly. But i'm only running elementary on desktop computers
