How to fix "Not Enough Free Disk Space On/boot" On Ubuntu"
Q: How can I fix the "Not Enough Free Disk Space On/boot" error On Ubuntu?

Today, I encountered the following error when upgrading Lubuntu 14.04, but it is very simple.

"Not Enough Free Disk Space On/boot"

This is because my/boot partition is full of old kernels and packages that are no longer needed.

 

Answer:

I have heard that the Computer Janitor function in Ubuntu Tweak can delete unwanted junk files. With Computer Janitor, you can clean up your system as it is installed. Janitor will delete:

• Program cache (Firefox/Chrome cache and Software Center cache );
• Thumbnail cache;
• Apt cache;
• Old kernel;
• Package configuration;
• A package that is no longer needed.

If you have not installed this tool, refer to the following link.

• How to install and use Ubuntu Tweak

To delete unwanted junk files, open Ubuntu Tweak and click the Janitor option.

Select the file you want to delete and click the Clean button.

Janitor is now cleaning up your system.

Cool! The system has been cleaned up.

I restarted and started software updates. This is no longer a problem.

That's it. Of course there are other ways to clean up the system. However, this method is easy to learn. We can just click a few times to clear the system.

Cheers!
