i attempted fixes suggested in posts found. nothing works me.

here more details:

$ gem list net  *** local gems ***  net-http-digest_auth (1.4) net-http-persistent (2.9.4) net-scp (1.2.1) net-ssh (3.2.0, 3.1.1) net-telnet (0.1.1) 

my capfile is:

my config/deply/production.rb file (one single uncommented line):

server '52.87.233.215', user: 'deploy', roles: %w{web app db} 

and config/deploy.rb file is:

don't know how fix , move forward?

when troubleshooting authentication failed errors in capistrano, useful drop down lower level , test connectivity ssh first. way can figure out if capistrano problem, or more basic ssh connectivity issue.

in case capistrano says cannot connect 52.87.233.215 deploy user. let's verify manually this:

ssh -v deploy@52.87.233.215 

the -v flag dumps bunch of verbose logging can see authentication methods being attempted.

if permission denied (publickey), indication not have public key installed on server. in other words, server has no way of verifying claim be, , denies access.

to install public key, copy contents of file from local machine:

~/.ssh/id_rsa.pub 

and paste contents file on server:

~deploy/.ssh/authorized_keys 

make sure ~deploy/.ssh/authorized_keys owned , accessible deploy user:

$ ls -ld ~deploy/.ssh drwxr-xr-x 2 deploy deploy 4096 jun 16  2015 /home/deploy/.ssh $ ls -ld ~deploy/.ssh/authorized_keys -rw------- 1 deploy deploy 1023 sep 12 02:13 /home/deploy/.ssh/authorized_keys 

now try ssh command again:

ssh -v deploy@52.87.233.215 

it should work, , if so, capistrano should work well.
