What do these command do?
sudo apt-get install linux-image-generic-lts-backport-natty \
linux-headers-generic-lts-backport-natty
Does it install just a new Linux version or something more?
And what about:
sudo apt-get purge linux-image-generic-lts-backport-natty \
linux-headers-generic-lts-backport-natty
Does it just remove the packages installed by the previous command? (or does it more?)
If I am correct in all cases why it doesn't work? I get an error, so it means it's not true and something else had happened?
Edit:
as it was said that second command doesn't remove it, then would this command remove it? aptitude autoremove
