I have been using ubuntu for almost 2 years now and I always encounter guides on the internet on how to uninstall old kernel versions. Even here in Ask Ubuntu there are many questions in this way.
My question is: Must I do so? Are there problems or could it be dangerous to leave these old versions installed? Are there any advantages?
Edit:
Just two points to clarify the question:
- I'm not asking instructions on how to remove old kernels.
- I'm not worried with the safety in remove the old kernels. Instead, I'm worried about the safety of leaving them installed.
