how do i free up space on my startup disk

When your startup disk is running low on space, it can be frustrating and even lead to system crashes or slow performance. Fortunately, there are several steps you can take to free up space on your startup disk.

Firstly, if you have already deleted old kernel packages (such as `linux-headers`), you may want to consider removing other unnecessary files and directories. One way to do this is by purging all but the last kernels with the command `sudo apt-get purge linux-image-generic-pae`.

However, this may not be enough to free up sufficient space on your startup disk. In that case, you may need to delete additional files associated with old kernel images. These files are usually stored in the `/boot` partition and can take up a significant amount of space.

To identify which files you can safely delete, you can use the `du` command to list the largest files on your system. For example, you can use the following command to list the 10 largest files on your system:

```

sudo du -a /boot | sort -n | tail

```

This will give you a list of the largest files in your `/boot` partition, along with their sizes. You can then delete any unnecessary files or directories that are taking up too much space.

It's also worth noting that if you have installed a newer kernel version through automatic updates, it's possible that the new kernel may still be using some space on your startup disk. In this case, you may want to consider reinstalling the older kernel version to free up more space.

By following these steps, you should be able to free up sufficient space on your startup disk and avoid any issues with your system performance.
