I briefly touched on my OpenSSH agent to WSL2 solution back in 2021. Today find myself setting up a new Windows 11 laptop and running into a couple of different issues, and ultimately using a slightly different solution than before, so here is the short writeup glossing over the areas that lead me to get a little stuck, and hopefully outlining a good set of commands.
In my old .bashrc file, I found a comment linking me to the rupor-github/wsl-ssh-agent GitHub repository which was my first set of reading, specifically the WSL2 compatibility section. The main sticking issue for me out of the box was a miss match in the OpenSSH version between Windows and WSL2, with Windows starting on 8.6 but WSL2 with Ubuntu starting on 8.9. This lead to errors such as:
- Error connecting to agent: No such file or directory
- error fetching identities: invalid format
- Could not open a connection to your authentication agent.
