I followed every single tutorial, and tried multiple different methods of authenticating my server's access to the github repo. All of it results in the same error, permission denied.
Last few lines after running cap roduction deploy:
INFO [4dcb4df3] Running /usr/bin/env git ls-remote firstname.lastname@example.org:EthanGroat/re-reddit.git HEAD as email@example.com DEBUG [4dcb4df3] Command: ( export RBENV_ROOT="$HOME/.rbenv" RBENV_VERSION="2.6.3" GIT_ASKPASS="/bin/echo" GIT_SSH="/tmp/git-ssh-re-reddit-production-ethangroat.sh" ; /usr/bin/env git ls-remote firstname.lastname@example.org:EthanGroat/re-reddit.git HEAD ) DEBUG [4dcb4df3] email@example.com: Permission denied (publickey).

I'm going quite insane. This stuff is unjustly difficult to set up, and there needs to be a more comprehensive guide. I followed both capistrano's and github's guides to the letter.
