This question already has an answer here:

"Not Enough Space"? I have plenty of space! What space is it talking about? How can I fix it?

Not too much additional info to give:

For starters, my /boot area is 243 Mib according to GParted.

  1. I clicked the Upgrade button on the Update window
  2. It proceeded to download some workfiles
  3. It started the Upgrade process
  4. Showed a dialog with a list of things it was going to do (Upgrading Ubuntu to version 13.04)
  5. Step 1 was finished OK (Preparing to upgrade)
  6. Step 2 almost finished (Setting new software channels)
  7. Then it crashed at sub-step "Calculating the changes"

Error text:

Not enough free disk space

The upgrade has aborted. The upgrade needs a total of 26.0 M free space on disk '/boot'. Please free at least an additional 5,029 k of disk space on '/boot'. Empty your trash and remove temporary packages of former installations using 'sudo apt-get clean'.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

This is a very vague answer, with little to no information to answer upon. Please elaborate more. – 16trohrt May 1 '13 at 1:13
By the way, I already tried the "sudo apt-get clean" with no change in the result. – Mauricio Verduzco May 1 '13 at 1:47
The error says "not enough free space", and not "not enough space". Your /boot might have 243 MB of size, but I guess only 20.9 MB is free out of those 243, and hence the installer complains. Can you verify this fact? – May 1 '13 at 2:15

Install ubuntu-tweak-tool in your current system. Open janitor, Check all options in system. It will remove old kernels from your /boot and lot's of space will be available after cleaning. You will able to upgrade system.

/boot is the partition which has the bootloader, kernels and all other important stuff. Perhaps you had installed updates so many times in the past and whenever the kernels are updated they dont delete the older versions. They leave them in /boot itself. Please delete older files from /boot. Your problem should be resolved.

This is how my /boot directory looks like. If I were to clean up, I would delete all the files which have in their names. Because, is, most likely, older than

Uninstall the kernels through the package manager. Don't just delete the files. – Mechanical snail May 31 '13 at 9:51
