Out of space /boot

**kr651129** · January 31st, 2013

I compiled a new kernel last night but when I tried to install it I'm being told /boot is out of space. I've never run into this problem in the past with Ubuntu.

A quick df -h tells me /boot has a total 228MB of space, 181 MB free. My disk is encrypted so I really don't want to have to boot from a live disk to resize the parition. Is there an easy solution for this?

Remove some old kernels. Synaptic PM works good for this.

Thanks for the reply, the problem is I only have one kernel on my machine. So I can't remove any old kernels.

Whats in your boot?

Code:

l /boot

Weird right?! I'm not sure off hand because I'm at work, I'll post the contents of /boot later tonight.

Why so small? I don't see how you can get around this problem other than to enlarge that partition.

Not sure, I went with the default options on the install for an encryped lvm volume. How hard will it be to resize this from a live usb image with it being encrypted?

That shows you have plenty of space and is consistent with 181/223 MB free.

How big is the kernel that you compiled? Did you strip all the debugging information from it? Is is compressed? Your vmlinuz should be about the same size as the one above, 5 MB.
