somehow all setup and start/stop script not work.

[malikshi]

i am running debian 11, all script seem won't work especially dnsproxy-setup.sh and dnsproxy-helper.sh

I've just edited the setup and helper scripts.

The setup script used to have Brace Expansion which works in bash but not sh in Debian.

You're probably using newer packages.
So, resolvconf is no longer provided on bullseye-backports and later.
It is now replaced by systemd-resolved.

I too have this issue too on Ubuntu Noble.
Since 22.10, it has also been replaced.

That means, the resolv.conf.d directory will no longer be generated or loaded from.
We'll need another way to add nameservers.
