That’s why we use the visudoprogram to open a text editor for checking errors in the configuration file during a file save. This is because we can inadvertently lock out a user or all users out of the system. A good example is when we had to input our user password when trying to view sensitive information earlier:įirst, let’s open our Linux terminal and type in the command below: $ sudo visudoīefore we continue, let’s keep in mind that mistakes in the /etc/sudoers file can be very costly. If youve already upgraded, run the above commands, then manually downgrade to the Trusty. This terminal enables us to write commands as input and get output. 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: sudo -S apt-mark hold sudo sudo -S apt-mark hold procps sudo -S apt-mark hold strace. According to man ssh, -A is supposed to forward local authentication, so it should be able to use sudo on the remote server. A short while later WITHOUT ANY CHANGES (on my part) the server remembers and the scripts start working again. But get the annoying sudo: no tty present and no askpass program specified when the script reaches a sudo. ![]() tty displays information on the terminal connected to our Linux system. But every so often, the server forgets and the script cannot execute and I get this error: 'no tty present and no askpass program specified'. You can fix it by either adding the command to your PATH or invoking it with an absolute path, i.e. ![]() The other command we’ll take a look at is tty.

In chroot environments, these other answers may not work correctly. yourExecutable This directs sudo to read the password from the standard input, stdin. Once we input the password, the system checks in the /etc/sudoers configuration file if the currently logged-in user has permission to make use of the sudo command. sudo: no tty present and no askpass program specified Alternate Answer. This is the content of my /etc/sudoers file: This file MUST be edited with the 'visudo' command as root. I’m using check_mk 1.2.2b5 with omd on CentOS 6.3.We can see from the above input that a prompt appears to insert the user password.
