• Issue with sudo – sudo:auth could not identify password for [user]

    If you get the following error when trying to execute a sudo command, despite the fact that you configured your sudoers or sudoers.d config file properly:

    sudo: pam_unix(sudo:auth): conversation failed
    sudo: pam_unix(sudo:auth): auth could not identify password for [user]

    Then, you might need to have a look at the PAM configuration on your device.
    Ensure that you have this line enabled in your /etc/pam.d/sudo file:

    # cat /etc/pam.d/sudo
    # The line below should fix the sudo:auth could not identify password
    auth       sufficient   pam_permit.so
    # The lines below are the default config
    auth       include      system-auth
    account    include      system-auth
    password   include      system-auth
    session    optional     pam_keyinit.so revoke
    session    include      system-auth

    Once you changed this file, no need to restart anything – just retry your command and it should work!
