Command `goal wallet new $NAME` fails with `inappropriate ioctl` error

[barnjamin]

Subject of the issue

When trying to create a new wallet through the sandbox, a prompt is displayed for the user to enter a password.

Because we dispatch the call with dc exec -T ..., no TTY is made available so an error occurs: inappropriate ioctl for device

Simply removing the -T flag from the dc subroutine allows it to work as expected but I'm sure causes issues elsewhere.

I think we'll need to figure out which goal commands require a TTY and when we see one, use the dc_pty subroutine

is there another way how to fix this issue?
