Hi, if you’re trying to build lemmy from scratch, on debian (not ubuntu), and you’re following this guide: https://join-lemmy.org/docs/en/administration/from_scratch.html

There are a few corrections I would like to point you.

Install those two things before following the guide:

apt install sudo

Of course, ‘sudo’ is not installed by default on Debian, so I guess it would be a good idea to install it.

sudo apt install build-essential

This will install the ‘cc’ compiler needed by Rust.

sudo apt install protobuf-c-compiler protobuf-compiler

This is needed to compile opentelemetry-proto.
