Allow Sudo Command Without Password step by step instructions. Similarly, for the packages you want, you should first look in the official repos, if they are there. So, on Arch Linux, the solution is to only use ALPM if you want to globally install stuff!įor numpy, there is python-numpy package in the official repos, so the correct way to install it is: sudo pacman -S python-numpy Even worse, you may have the wrong version of numpy installed, so even if you manage to make it work, FreeCAD might have unpredictable errors – this is very similar to a partial update situation. The first method is to log in as the root user without worrying about further authentication. But package python-numpy uses the same files you’ve already installed with pip, but ALPM did not know that. 1 Execute specific commands without sudo password in Ubuntu 2 Find the path to the command and add it to the sudoers file 3 Ask for the sudo password for a. This article covers two methods of using the sudo command without having to enter password. Why? Because package freecad has package python-matplotlib as a dependency, and the package python-matplotlib has the package python-numpy as a dependency. ![]() You would try sudo pacman -S freecadĪnd you’d get a bunch of errors. ![]() It may work at first, but let’s say you wanted to install FreeCAD. Instead of editing the sudoers file you can create a new file with the authorization rules in the. The sudoers file contains information that determines a user’s and group’s sudo.

Specifically I want passwordless sudo for this new user. I want to add a new user that has the same behavior as the default Ubuntu user. If the user is in the admin group, and you want the user to run all commands without a password you want: admin ALL (ALL) NOPASSWD:ALL. 283 How does the ubuntu user on the AWS images for Ubuntu Server 12.04 have passwordless sudo for all commands when there is no configuration for it in /etc/sudoers I'm using Ubuntu server 12.04 on Amazon. We must stress that this removes this last protective barrier between a user and their own mistakes. In the sudoers file add the NOPASSWD: tag infront of the commands you want to be able to use. And that’s because one wrong command can lead to the deletion of all our data, the destruction of our installation, or the unintended sharing of personal information.ĭisabling the sudo password is only good for those who have a good experience with the Linux command line and are the only user on their computer. Instead, it’s there for the same reason as Windows’s annoying User Account Control: as a last protective layer between us, our computer, and potential chaos.
