A A note on sudo
Raspberry Pi OS (and previously Raspbian) allows the default user to run sudo without a password. This is not true for other Linux distributions, such as Ubuntu. This could lead to a password prompt when using scripts such as sr
and ws-indicate
. As nodes are designed to run autonomously, the installation process for ws-node
will configure these scripts to not require a sudo
password.
In some installations (generally where the devices are managed by organisations) the sudo
group will not be present. To allow running without a password the file /etc/sudoers.d/ws
can be renamed (to avoid changes being undone if ws-node
is re-installed) and the %sudo
group modified to an appropriate group present on the system.
