I did a clean install on my Mac, and reinstalled ruby properly, using rvm, though now I have an issue with Capistrano in all my bedrock sites.
I installed gems needed for bedrock/capistrano deploy, with
bundle install. My gemfile and capfile are largely base on these ones: https://github.com/roots/bedrock-capistrano.
Now, since the clean install, Capistrano deployment fails while using gems sshkit-1.19.1 / net-ssh-5.2.0, needing more gems (this was not the case before).
~/.rvm/gems/ruby-2.5.6/gems/net-ssh-5.2.0/lib/net/ssh/authentication/ed25519_loader.rb:21:in `raiseUnlessLoaded': OpenSSH keys only supported if ED25519 is available (NotImplementedError) net-ssh requires the following gems for ed25519 support: * ed25519 (>= 1.2, < 2.0) * bcrypt_pbkdf (>= 1.0, < 2.0)
After adding the above gems to my bundle and successfully performing a bundle install, I get a new error.
Enter passphrase for ~/.ssh/id_rsa: #<Thread:0x00007fb6ed16fc00@~/.rvm/gems/ruby-2.5.6/gems/sshkit-1.19.1/lib/sshkit/runners/parallel.rb:10 run> terminated with exception (report_on_exception is true): Traceback (most recent call last): 1: from ~/.rvm/gems/ruby-2.5.6/gems/sshkit-1.19.1/lib/sshkit/runners/parallel.rb:11:slight_smile: `block (2 levels) in execute' ~/.rvm/gems/ruby-2.5.6/gems/sshkit-1.19.1/lib/sshkit/runners/parallel.rb:15: in `rescue in block (2 levels) in execute': Exception while executing as email@example.com: undefined method `' for nil:NilClass (SSHKit::Runner::ExecuteError) (Backtrace restricted to imported tasks) cap aborted! SSHKit::Runner::ExecuteError: Exception while executing as firstname.lastname@example.org: undefined method `' for nil:NilClass Caused by: NoMethodError: undefined method `' for nil:NilClass
Edit: This error was due to something going wrong with my ssh private/public rsa keypair. After creating a new keypair, the issue was solved.
