I have made Ubuntu my primary OS since 10.04, and I have converted many of my friends and neighbors into Ubuntu users since then. I am the fix-it guy they approach when they encounter problems. The most frantic calls I get are when they encounter an "update-induced kernel panic." (Many human beings are allergic to command-line interfaces and search engines.)
What are the step-by-step procedures to resolve an "update-induced kernel panic"?
My ideas:
Make sure you always keep at least one older and stable kernel version installed.
That way, if a new kernel update causes the panic, you will still be able to restart your system with the old one.
Write down as much information as you can regarding the error.
Take a photo of the screen output with your mobile phone perhaps.
Post these messages here or in other related forums so that someone else can help you out.
Keep an Ubuntu Live-CD always close.
A package update might screw things up, but you'll still be able to boot and through a chroot make the necessary uninstallation/reinstallation of the package.
