Error: OpenSSH keys only supported if ED25519 is available

[paulmist]

OS: macOs Catalina 10.15.4
Ruby: 2.6.3p62
Wordmove: 5.0.2
Using RVM

I've got a new install on a new mac - hitting the following problem when trying to push a database.

OpenSSH keys only supported if ED25519 is available (NotImplementedError)
net-ssh requires the following gems for ed25519 support:
 * rbnacl (>= 3.2, < 5.0)
 * rbnacl-libsodium, if your system doesn't have libsodium installed.
 * bcrypt_pbkdf (>= 1.0, < 2.0)
See https://github.com/net-ssh/net-ssh/issues/478 for more information
Gem::MissingSpecVersionError : "Could not find 'rbnacl' (>= 3.2.0, < 5.0) - did find: [rbnacl-5.0.0]
Checked in 'GEM_PATH=/Users/paulmist/.rvm/gems/ruby-2.6.3:/Users/paulmist/.rvm/rubies/ruby-2.6.3/lib/ruby/gems/2.6.0', execute `gem env` for more information"

Have tried installing the mentioned gems rbnacl (5.0), rbnacl-libsodium, bcrypt_pbkdf.

No change.

Hi already tried to read this related issue #510 ?

[alessandro-fazzi]

BTW I think that it's a https://github.com/welaika/photocopier 's fault.

I'd be ok to try to update its dependencies, just want to be sure that you already followed past troubleshooting paths. :)

Let me know

[paulmist]

As per #510 (comment) the issue appeared to be related to macOs no longer keeping my SSH key persistent after a reboot.

Fixed using https://apple.stackexchange.com/questions/48502/how-can-i-permanently-add-my-ssh-private-key-to-keychain-so-it-is-automatically

Thanks a lot for sharing your solution :)

@pioneerskies Tried wordmove and I'm also hitting this and not on mac. Tried the fix metioned by @paulmist but I still get this error when trying to do a pull against a google cloud instance (the mysqldump step is failing) so I think it might be an issue with photocopier as you mentioned.

rsync steps seems to run fine.

Ok, got it working. I used the docker image welaika/wordmove

To get it working against an ssh host with ed25519 key, I had to add launch the ssh-agent: eval `ssh-agent -s and add ~/.ssh/config with:

Host *
  AddKeysToAgent yes

[alessandro-fazzi]

@gormv if you modified the image in order to eval ssh-agent -s, you may be interested in discuss about that into the image's github repo.

Thanks for sharing
