Install SOPS without root

[hack3d]

It's currently not possible to install sops without root permissions if dpkg is installed.

It's possible to workaround this by creating an empty sudo binary

echo "exec $*" > /usr/bin/sudo && chmod +x /usr/bin/sudo
helm plugin install https://github.com/futuresimple/helm-secrets

Running this will remove the actual sudo binary if it already exists though, so be careful if the system has/needs sudo
