Can't upgrade because /boot partition is full

[moondoggy2]

I've been trying for the last few days, to update my copy of Trusty. It won't work, because I'm told my /Boot partition is full.
I am unable to manually delete the old images. I can't move them to a different location. 251454
I've cruised the net looking for solution after solution, and nothing has worked. I've tried purging them, to no avail. I've tried 'sudo apt-get autoremove' and nothing worked. I tried 'sudo apt-get --purge autoremove' and nothing worked.
Any help would be greatly appreciated, fellas.

I generally do not suggest separate /boot partitions just for the issues you are having.

If you can boot or chroot into your system. I ran these commands from my working system, if you only have command line then you cannot use nautilus to delete kernels. Obviously change fred to your username.


1253 dpkg -S /usr/src/*
1254 uname --kernel-release
1255 sudo apt-get update
1256 sudo apt-get upgrade
1257 sudo apt-get -s autoclean
1258 sudo apt-get autoclean
1259 sudo apt-get -s autoremove
1260 sudo apt-get autoremove
1261 df -h
1263 gksudo nautilus
1268 sudo chown -R fred /root/.local/share/Trash/
1274 sudo rm -rf /root/.local/share/Trash/
1275 df -h
1276 history

I gernally prefer to use synaptic. But if you upgraded, you may have old kernels from previous installs that are now not in dpkg to remove and have to manually remove them.
Determine your current kernel:
uname -a
uname -r
In synaptic search for linux-image to choose to delete old ones

cd /boot
ls vmlinuz*
sudo apt-get purge linux-image-[version]-generic linux-image-[version]-generic
Multiples, just be sure not to delete your current kernel:
sudo apt-get purge linux-image-3.5.0-{XX,XX,XX,XX,XX,XX}-generic
Example:
sudo apt-get purge linux-image-3.5.0-{17,18,19,21,22,23,24}-generic

If the only way you can get into system is with chroot from a live installer, these are examples of chroot to do other tasks as well. You do not need sudo once chrooted.

dpkg -S /usr/src/*
uname --kernel-release

If you can still boot your system then you can also remove the old kernels with this:

sudo dpkg -l linux-* | awk '/^ii/{ print $2}' | grep -v -e `uname -r | cut -f1,2 -d"-"` | grep -e [0-9] | xargs sudo apt-get -y purge
sudo apt-get update && sudo apt-get dist-upgrade

Tell us if it helps... if it doesn' t then you will have to follow oldfred's advice.
