Question

all of a sudden Capistrano fails to deploy to production

Hi, for some reason, Capistrano fails to deploy my website to my production server (Ubuntu 14) on Digital Ocean.

the error message is:

fatal: Could not read from remote repository.

I’m a bit puzzled, this always worked until now.

Last week I did an update of OSX on my local dev machine. Maybe that got something to do with it

Anyone had the same experience where Capistrano couldn’t read from the remote repository for no apparent reason?

thanks for your help,

Anthony

Hi asb,

I can push to my remote repository with Git, but when I run this command:

ssh -vvv git@github.com

I’m seeing this error message in the output:

Connection established.
debug3: Incorrect RSA1 identifier
debug3: Could not load "/Users/myusername/.ssh/id_rsa" as a RSA1 public key

greetings,

Anthony
