A simple way is to specify -t:
From the man page:
Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g. when implementing menu services. Multiple -t options force tty allocation, even if ssh has no local tty.
I cannot explain exactly why this works, and there may be a better way. I'd like to hear about it if so :)
@psusi explains why this works in a comment below.
Drew NoakesDrew NoakesHow can I work around this?
As an alternative, try:
sudo -S ./binary
This directs sudo to read the password from the standard input, stdin.
In chroot environments, these other answers may not work correctly .. perhaps because:
- /etc/shadow vs /etc/passwd conflict not allowing the user to enter a password.
- In a chroot-ed environment, access to tty1 can be a bit glitchy, and ctrl-alt f2 -- to tty2 is unfeasible, because it is a tty of the non-chroot-ed environment.
For example: Manually installing / repairing linux or the bootloader, using a chroot environment, (such as Archlinux and arch-chroot).
You need to define terminal/application that will read the password. There are two variants:

export SUDO_ASKPASS=/usr/libexec/openssh/ssh-askpassvim /etc/sudoers(Defaults visiblepw)
It fails, because sudo is trying to prompt on root password and there is no pseudo-tty allocated.
You've to either log-in as root or set-up the following rules in your /etc/sudoers (or: sudo visudo):
Then make sure that your user belongs to admin group (or wheel).
kenorbIn my case I've received this error because I wasn't specifying a command that I would like to use as root in the sudoers
Something like
/etc/sudoers.d/myuser:
worked for me
Drew NoakesYou can also create a file like 'sudo_shutdown' in /etc/sudoers.d, with content:
This allows users which are in the adm group to shutdown without a password.

So silly, after looking further down I see a solution from Beorat:
To avoid the sudo tty issue and others, run these commands just before running do-release-upgrade:
If you've already upgraded, run the above commands, then manually downgrade to the Trusty packages:

Chris RogersChris RogersWSL uses the lxrun executable for management from Windows:
lxrun -h
Given that, you can use lxrun /setdefaultuser root. Just thought I'd point out this side of it since it was required when I ran into the same issue as you after trying to upgrade to Xenial. I can confirm that running this command, then the wget / dpkg commands my issues were resolved.

cchamberlainI got rid of the error by moving /etc/hosts to /etc/hosts.bu. After closing the shell en opening again, /etc/hosts is recreated and your computer name is added. The error is gone (for me.)
