Cannot Run Update Manager or Package Manager

Thank you for taking the time to report this issue and helping to make Ubuntu better. Examining the information you have given us, this does not appear to be a bug report so we are closing it and converting it to a question in the support tracker. We appreciate the difficulties you are facing, but it would make more sense to raise problems you are having in the support tracker at https://answers.launchpad.net/ubuntu if you are uncertain if they are bugs. For help on reporting bugs, see https://help.ubuntu.com/community/ReportingBugs#When%20not%20to%20file%20a%20bug.

Your hard disk is full. Try to delete some files you don't need anymore, run "sudo apt-get clean" or the computer janitor.
If the error persists post the output of the command "df"!

Open a Terminal from the menu Applications → Accessories → Terminal and type:

lsb_release -r

Then please copy and paste output here...

Thank you

Release: 9.10

I checked the drive spaces:

File Resources 4.0 GB Free
System Resources 75 MB

I still get this error after running the previous commands:

gzip: stdout: No space left on device
update-initramfs: failed for /boot/initrd.img-2.6.31-14-generic
dpkg: subprocess installed post-installation script returned error exit status 1

Not sure what you mean by "If the error persists post the output of the command "df"!"

To get more space try...
