tasks

set :rails_env, "trunk"
I have deployed this application numerous times successfully to all
environments. In my other apps, I have been locking the capistrano gem to
2.14 as we use subversion and there's a bug in 2.15 (and 3.x is obviously
out) and I was making the pass on this one today. I was also doing some
other things and emptied its gemset and re-installed it using bundle
update. And then when I went to deploy, this (deploy:check in the example
as it's a lot shorter):
$ cap deploy:check
triggering load callbacks
triggering start callbacks for `deploy:check'
* 2014-02-03 16:34:28 executing `multistage:ensure'
*** Defaulting to `trunk'
* 2014-02-03 16:34:28 executing `trunk'
* 2014-02-03 16:34:28 executing `deploy:check'
* executing "test -d /var/www/graphene/trunk/releases"
servers: ["foo.bar.net"]
connection failed for: foo.bar.net (Net::SSH::AuthenticationFailed:
Authentication failed for user [email protected])
Googling around I find that the likely cause is I
need default_run_options[:pty] = true set, except, it is indeed set in my
Capfile. (Tried in deploy.rb, also, just to be sure.) When I went to one of
my other apps, they deployed fine. When I went to a tag of this app that I
just recently deployed, it also deployed fine. On looking at the gem list,
I saw the problematic app had was using net-ssh (2.8.0) the happy app was
using net-ssh (2.7.0). Seeing as net-ssh was mentioned explicitly in the
error, I uninstalled 2.8 and installed 2.7, and sure enough I got the
expected password prompt when carrying out a deploy.
So this is not so much a question as an observation that could possibly
help someone else who is scratching their head.
