sudo: no tty present and no askpass program specified

[willemx]

This error message appears when running "mup setup" on my Mac to setup my Ubuntu linux machine for mup deployment.
I'm using ssh based authentication (which works fine when I open a ssh terminal session from my Mac to the Ubuntu server)
After hours of googling and experimenting with no luck so far, I now must bow my head in shame and ask for some kind advice...

I can confirm this error message on Ubuntu 14.04 server.

You can use the root account on ubuntu as a workaround.

I had the same error, and am using root as a workaround as well.... but I'd prefer not to...

[arunoda]

You don't need to be root. But create an user and allow him to login with SSH keys and make sudo password less.

[arunoda]

BTW: Since Meteor needs port 80, that's why we need root like permission. But just after we bind to the port, your app will step down to a lower permission group.

So, if someone breach into your app, he will have some hard time.

@arunoda Thank you, that is good to know.

As @arunoda said, run sudo visudo and edit the file to be sure that your user can run sudo with no password:

# replace this line
%admin  ALL=(ALL) ALL

# by this line
%admin ALL=(ALL) NOPASSWD:ALL

And then:

sudo service sudo restart

@LeCoupa +1 for your solution (it would be a good idea to add this in the readme I guess?)

[arunoda]

@LeCoupa can you send me a PR with this added to the README.

Add under this: https://github.com/arunoda/meteor-up#setting-up-a-server

Actually, I run my meteor app behind an apache server on 80, so I specified PORT: 3000 in my env block. I got all the way to when I think it is starting the server and poof, it requires sudo.

I'd prefer not to give my user sudoers at all, and if the port requirement is > 1024, then I don't think it should try to elevate with sudo.

I was able to get all the directory perms setup for the scp and file juggles, but this last problem confounds me.

I have found this dude, who lets node bind to any lower port, but I don't like that solution either

Ok i have been trying to get around this for 6 hours, i am stumped guys. I know this an old one, but its still open and it is making my life sad.

I edited sudoers via sudo visudo to insert to modify sudo and admin group as noted above, and have read about about 20 forum threads top to bottom. Am i missing something? Well, clearly i am. I have created lots of new users on ubuntu vm to try different solutions in isolation, just don't know what else to do.

I am about to just skip mup and try to deploy manually with demeteorizer, not the solution i was hoping for :(

[alexdmejias]

+1, which is annoying because I have made it work previsouly

[MasterJames]

Did you try mupx and follow migration?

[bgazzera]

@AWI-Koleok Surely you have moved on, but this worked for me.

The instructions on https://github.com/arunoda/meteor-up
say:

sudo visudo

# replace this line
%sudo  ALL=(ALL) ALL

# by this line
%sudo ALL=(ALL) NOPASSWD:ALL  

Note that this is different from the solution above.
