apt install fails on noetic (testing)

Timple commented 3 years ago

Can be reproduced by this minimal dockerfile:

FROM ros:noetic-robot
RUN sed -i 's|ros/ubuntu|ros-testing/ubuntu|g' /etc/apt/sources.list.d/ros1-latest.list
RUN apt-get update -qq && apt-get install -y ros-noetic-hector-gazebo-plugins

Outcome:

Step 3/3 : RUN apt-get update -qq && apt-get install -y ros-noetic-hector-gazebo-plugins

I've noticed this in a different context but this is not caused by us. There are some shenanigans going on with the gazebo11 packages. Seems like a version conflict in one of gazebo's dependencies. (If this is the same problem, you're encountering.) I've done the command in an interactive docker container:

Aha, maybe related to this then: https://github.com/ros/rosdistro/issues/27851

StefanFabian commented 3 years ago

No, that issue only results in me getting daily emails from the build farm :( It appears that the gazebo packages were built against newer versions of the libignition libraries than are available in the ubuntu repositories. It needs >=3.12 but only 3.11 is available.

Timple commented 3 years ago

So the rosdistro repo would be the best place for this issue?

StefanFabian commented 3 years ago

There seems to be an issue in the gazebo repository already osrf/gazebo#2995

Verified to be working again
