Add a troubleshooting guide

[jamiemonserrate]

Describe the solution you'd like
Can we add a troubleshooting guide with the most common errors folks run into? Ideas to include

• how to debug a kube-vip not working scenario
• pre-requisites not installed on the host
• how to debug installer failures

do you have estimation when such guide will be released?
I am currently trying to deploy a cluster using the byoh provider and I have a scenario where kube-vip is not working, and I am not sure how to debug it.

We are aiming to get this done in the next couple of months. But in the meanwhile, we are happy to try to help you over Slack. Would you mind starting a thread in #cluster-api-baremetal on the kubernetes slack and tag @Anusha Hegde @dharmjit @jamie Monserrate, and we could help you get unblocked.

thanks,
Keren

Hey @kerenbenzion ,
I see that you are trying to delete byohosts as mentioned in this issue here, so I'm hoping you got past the kube-vip issue? If not feel free to post your queries / errors / logs here or on slack (#cluster-api or #cluster-api-baremetal)

Add to the troubleshooting guide -
If your host linux is other than Ubuntu 20.04, say Ubuntu 18.04, then you may encounter this error while executing make prepare-byoh-docker-host-image

E: Unable to locate package linux-image-4.15.0-161-generic
E: Couldn't find any package by glob 'linux-image-4.15.0-161-generic'
E: Couldn't find any package by regex 'linux-image-4.15.0-161-generic'
