Fails to connect to known host with ed25519 fingerprint

[trevarj]

If you have already connected to a server over ssh and saved a ssh-ed25519 fingerprint in ~/.ssh/known_host then doing :DistantLaunch [host name] fails to read the fingerprint.

Failed (1): Failed to launch server
Caused by:
    Fatal: host verification: host key mismatch for ssh server 192.168.1.1:22.
    Got fingerprint SHA256:7Bekk1Nx0yOKspOjOHEw+RfeaC2K9NDg51BUoVZEWBI instead of expected value from known_hosts
    file ~/.ssh/known_hosts.

Tried using v0.2 branch

Whoops, had a reply waiting for this and never sent it. Thanks for the port, @trevarj!

I've seen this happen and not sure why. My workaround was just to delete the entry from the known_host file and recreate it as part of :DistantLaunch.

You could try changing the backend that powers the ssh functionality by doing :DistantLaunch options="ssh.backend=libssh" and see if that helps.

Yep, this is what I ended up doing too. It recreates with a ecdsa key, so my guess is the default ssh backend must be expecting only that.

Closing out as an outdated issue. There's a workaround included in this issue, and this may also get resolved with chipsenkbeil/distant#193 for distant.

Nothing else that can be done in the neovim plugin itself.
