![]() ![]() Note: this is more for the sake of exeprimentation and learning than any practical purpose, I'm not trying to find out how to use sudo with rsync, I've already read all I could find about that. The build script contains sudo calls for which it does not say 'sudo: no tty present and no askpass program specified'. When I check out the source code and run my build script, it works fine. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g. It fails, because sudo is trying to prompt on root password and there is no pseudo-tty allocated. The only way I think of doing something like that would be to use an expect script around sudo, which reads the password from a named pipe, and I would write to that pipe from the other terminal. I have one build machine which has a user abc which is has limited sudo access. sudo: no tty present and no askpass program specified then you can easily find the solution: add the -t option to your ssh command:-t Force pseudo-terminal allocation. When running any sudo command from Jenkins I get the following error: sudo: no tty present and no askpass program specified. That way, I could run rsync in one terminal window on my local machine, and use another terminal window to open a (possibly separate) ssh connexion to the server, and supply the sudo password there. How can I instead tell sudo to read its password from, say, another TTY ? ![]() So I had to add this to /etc/sudoers (using sudo visudo), which basically gives passwordless full read-write access to the system to the user rsyncuser, which is not to my taste: rsyncuser ALL= NOPASSWD:/usr/bin/rsync But I got the infamous error: sudo: no tty present and no askpass program specified 1 02-21-2010 linuxgeek Registered User 78, 0 sudo: no tty present and no askpass program specified Hi Gurus: Can you help me get out of this message I already commented out the ff line in /etc/sudoers file but still prompts me for this message. Ideally, that command would ask my private ssh key password, then connect, then ask the sudo password for rsyncuser, and then run rsync on the server. ![]() => Builds finished but no artifacts were created.I want to setup rsync backups of my server, so I run the following command rsync -r -e ssh -rsync-path="sudo rsync" /backup/ > Ubuntu-18.04: Script exited with non-zero exit status: 1.Allowed exit codes are: => Some builds didn't complete successfully and had errors: => Wait completed after 8 minutes 21 seconds => Ubuntu-18.04: Destroying virtual machine.īuild 'Ubuntu-18.04' errored after 8 minutes 21 seconds: Script exited with non-zero exit status: 1.Allowed exit codes are: => Ubuntu-18.04: Stopping virtual machine. => Ubuntu-18.04: Provisioning step had errors: Running the cleanup provisioner, if present. => Ubuntu-18.04: sudo: no tty present and no askpass program specified In chroot environments, these other answers may not work correctly.

See SSH inside SSH fails with 'stdin: is not a tty' for a more detailed explanation. ![]() If you pass a command to ssh, it assumes that the command doesn't need a terminal and doesn't create one, unless you pass -t. => Ubuntu-18.04: Provisioning with shell script: /tmp/packer-shell382031289 sudo: no tty present and no askpass program specified Alternate Answer. 1 Answer Sorted by: 0 Without knowing the library or application your Windows application uses, your best guess would be to set the TERM variable to xterm: export TERM'xterm' If that doesn't give you the desired results, refer to the manual of your library/application and find the terminal emulation type there. You need to have a terminal available to run sudo so that it can prompt you for the password. => Ubuntu-18.04: Waiting for SSH to become available. => Ubuntu-18.04: Typing the boot command over VNC. This is the full error: => Ubuntu-18.04: Connecting to VNC over websocket. In ESXi I see the VM build and complete and reboot and it gets an IP and I get a SSH prompt briefly before Packer deletes the VM after I see the above message. I did: sudo usermod -a -G dialout zabbix So modbus. update, i tried again the modbus.get e now a got this. I'm simply trying to deploy a Ubuntu 18.04 VM however at the end of the build I get this error in the packer console: sudo: no tty present and no askpass program specifiedĬommand I run: sudo packer build -var-file=variables.json build.json sudo: no tty present and no askpass program specified Ty Hamardaban i appreciate your tips. I'm been learning how to use Packer this week on my home lab where I have an ESXi 7 host. ![]()
