NotImplementedError: OpenSSH keys only supported if ED25519 is available
net-ssh requires the following gems for ed25519 support:
* ed25519 (>= 1.2, < 2.0)
* bcrypt_pbkdf (>= 1.0, < 2.0)
See https://github.com/net-ssh/net-ssh/issues/565 for more information
Gem::LoadError : "ed25519 is not part of the bundle. Add it to your Gemfile."
Solution 1:[1]
For me just execute on terminal
ssh-add
And this worked.
Solution 2:[2]
On Mac OS at least, you'll get this error if you don't ssh-add [yourkey] after system startup.
Solution 3:[3]
Although you can get around this error by adding the gems suggested by the other answers, you don't necessarily need to do it this way.
An alternative is to follow the advice given in the Known Issues for Puppet's Bolt tool, in particular this one.
Just in case that link disappears, the solution is to generate your SSH keys in the PEM format rather than OpenSSH. You can do this by adding an extra option to your ssh-keygen command:
ssh-keygen -t rsa -m PEM
I've been able to successfully use this technique to avoid adding the extra gems.
Solution 4:[4]
My working solution:
Gemfile
gem 'net-ssh', '>= 6.0.2'
gem 'ed25519', '>= 1.2', '< 2.0'
gem 'bcrypt_pbkdf', '>= 1.0', '< 2.0'
Solution 5:[5]
Add those gems to your Gemfile,
gem 'rbnacl', '< 5.0', :require => false
gem 'rbnacl-libsodium', :require => false
gem 'bcrypt_pbkdf', '< 2.0', :require => false
and then run bundle install and try again.
Solution 6:[6]
This solved the same issue with me
ssh-agent -s && ssh-add ~/.ssh/id_rsa
Solution 7:[7]
In a multi user developement server, without root permission, this solved:
eval `ssh-agent -s`
ssh-add
