The Problem

I ran into an issue with SSH login without a password. I had set up the passwordless SSH login for several uses; however, one user refused to work. After setting up SSH Login Without a Password I was still prompted for a password. The first step was to determine why I was still being challenged for a password and to do this I needed to enable DEBUG output for SSH on the server to see what was going on.

This post shows how to remove (clean up) old kernels. Old kernels (to me) are defined as kernels that are installed on your system but no longer needed/used.

You can use a package manager (such as synaptic) to remove old kernels, simply search for linux-image or linux-headers that are installed and remove them. Also of importance is to note that you should remove old kernels and headers together as one is not useful without the other in most circumstances.

I have a triple boot setup (Xubuntu, LMDE, and crunchbang) on my primary work laptop and have ran into several occasions when an update (always LMDE) breaks GRUB. This article explains how to fix a broken GRUB on a system with several operating systems, all using separate partitions for root (/), boot, home, etc.
