Building: Rosdep can't locate packages

[edwardribbit]

I'm trying to build the package for the first time in my ros workspace and I'm trying to get the dependencies using rosdep.

The command I'm using is: rosdep install -r --from-paths src --ignore-src --rosdistro humble -y

I've already ran rosdep init and rosdep update.

/etc/ros/rosdep/sources.list.d/20-default.list :

# os-specific listings first
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/osx-homebrew.yaml osx

# generic
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/base.yaml
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/python.yaml
yaml https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/ruby.yaml
gbpdistro https://raw.githubusercontent.com/ros/rosdistro/master/releases/fuerte.yaml fuerte

# newer distributions (Groovy, Hydro, ...) must not be listed anymore, they are being fetched from the rosdistro index.yaml instead

The error I'm seeing from the rosdep install command is

rosdep install -r --from-paths src --ignore-src --rosdistro humble -y

What should I do so that the packages can be located by rosdep?

It's working after adding the ros2 gpg key with apt following the ros2 install instructions
