I got the following error message from Software Updater:

The upgrade needs a total of 74,6 M free space on disk '/boot'. Please free at least an additional 68,3 M of disk space on '/boot'. Empty your trash and remove temporary packages of former installations using 'sudo apt-get clean'.

How can I get more disc space? I have

The suggestions in the notice are not enough? –  Rinzwind Jul 10 at 8:18
well /boot is almost full, 98%, which means you have almost no disk space. Did you even read the message? –  Alvar Jul 10 at 8:25
@Alvar I read but somehow I thought it is enough to empty the trash on the desktop. Well, by emptying the boot directory helped. –  user2219896 Jul 10 at 8:28
run the command suggested sudo apt-get clean and delete old kernels. Make sure you keep the one you are using and I suggest you keep the previous one but delete all others as described here –  Warren Hill Jul 10 at 8:47
You have a seperate partition for /boot, so it only has a certain ammount of space (273MB). Everytime there is a new kernel, and you update to it it creates a file in /boot, over time and by not removing old kernels this will fill up. run "sudo apt-get autoremove" then "sudo apt-get autoclean" and it will probably be okay. –  robblue2x Jul 10 at 9:14

I experienced this same message with Ubuntu 14.04. The answer to this question took care of the problem by removing old Linux kernels from /boot. It freed almost a half gig of space there.

Here's the link: How do I remove or hide old kernel versions to clean up the boot menu?
