EC2 machine on aws is filled with multiple linux headers and currently / is 100% full on disk space. I ran commands like apt-get autoremove but it is throwing an error saying

No apport report written because the error message indicates a disk full error
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)

Can I remove the old headers by the rm command? Is it safe? and if I remove with rm command, should I do any clean up after that? Here is the list of headers:

To delete linux headers safely, always use:

$ sudo apt-get autoremove

Sometimes this command can give error like this:

Reading package lists... Error!
E: Could not create temporary file for /var/cache... (28: No space left on device)
E: The package lists or status file could not be parsed or opened.

In this case, delete one or two old headers manually. To do this first go to /usr/src folder and list the files according to date (oldest last) using below commands:

$ cd /usr/src
$ ls -lt

Then choose an old header (e.g. linux-aws-headers-4.4.0-1067) and delete it:

$ sudo rm -r linux-aws-headers-4.4.0-1067

After doing this, the command sudo apt-get autoremove should work without any problem.
