[Enhancement] Add troubleshooting subsection to `Remote Deployment` #110

Closed piyoki closed 8 months ago

piyoki commented 8 months ago

Proposal

Add an addtitional troubleshooting subsection in Remote Deploy followed by Deploy through nixos-rebuild. Also, include workarounds to SSH related issues that end-users might encounter.

Background

Recently, I've decided to give colmena a try. In general, everything works as expected. Yet, I do have a few complaints when it comes to troubleshooting.

An issue I recently found was that if a host's IP has been changed over time (VM environment), we are supposed to remove the host entry in $HOME/.ssh/known_hosts on the host machine (Laptop | Desktop). Otherwise, colmena will complain not be able to remote SSH connection denied.

Workaround

ssh-keygen -R <remote-machine-ip>
