SUDO Problem

[partydrone]

When trying to deploy to a new staging server, I get the following
error:

sudo: no tty present and no askpass program specified

Anyone know what's up with this and how do I fix it?

Thanks!

You do not have a tty (you are therefore using a pty) -- and you do not have passwordless sudo access configured.

You can alter capistrano's configuration to use the other (a tty, or a pty, whichever your configuration requires)

I just bit by the same problem connecting to Ubuntu 9.10 (Karmic
Koala).

I think this is going to affect all Capistrano users who use sudo in
recipes.

Capistrano supports sudo with passwords and ubuntu has always granted
a pty when you ssh to it.

Any idea what may have changed in last weeks release of Ubuntu?

No Mike, but I'd love to know, if you come across any evidence, I'd really appreciated if you shared it on here; we've been saying for a long time that using sudo during deployment encourages insecure/unsafe setups (and of course, means that we're making assumptions that don't apply to a /lot/ of people on shared hosting.. so this may yet change)

[Mike Bailey]

sudo is necessary in some circumstances (such as creating a user or installing a package)

I've been having a look into this and found that the password prompt for sudo doesn't seem to be working on a host I've been using since 2006.

maculike:~ mbailey$ cap test_sudo HOSTS=sh01
    triggering load callbacks
  * executing `deprec:connect_canonical_tasks'
  * executing `test_sudo'
  * executing "sudo hostname"
    servers: ["sh01"]
    [sh01] executing command
*** [err :: sh01] Password:
my_password     

Has something changed in Capistrano that broke entering my sudo password? I'm using capistrano-2.5.9

Nothing changed Mike, but passworded sudo access isn't supported officially, because it's so damned difficult to get right across multiple platforms.

The following error appears when Capistrano attempts to use sudo with a password on Ubuntu 9.10 "Karmic Koala":

sudo: no tty present and no askpass program specified

This can be solved by setting the following variable:

default_run_options[:pty] = true

You can do this in your ~/.caprc file, /etc/capistrano.conf, ./Capfile, or deploy.rb

Thanks to Lee for pointing this out

I thought we solved it a while ago by using #{sudo} in commands:

run "#{sudo} hostname"

instead of:

run "sudo hostname"

What platform does it not work on?

This is actually why my test task failed on the server from 2006. I was tired and forgot to use #{sudo}. :-)

Mike,

Sure, it's supposed to be like the way you just explained it - glad we didn't break anything for you :-D

Thanks a lot Mike, this helped a lot!

This did it for me.. Now I can deploy! Thank you
