The Linux system (and especially the sudo command) is pretty picky when it comps to ownership rights etc. As for your sudo problem see this link: chown root:root /etc/sudoers chmod 440 /etc/sudoers chown -R root:root /etc/sudoers.d chmod 755 /etc/sudoers.d chmod 440 /etc/sudoers.d/* If you’re as unlucky as I was then you might run into some more troubles when other parts of the Linux system start noticing that you messed up the rights in the /etc/ folder.
