2021-05-26 15:42:14 -0500	marked best answer	ROS2 Eloquent installation failed in Ubuntu 18.04.4 LTS Referring to link:https://index.ros.org/doc/ros2/Installation/Eloquent/Linux-Install-Debians/ I am installing ROS2 Eloquent into my Ubuntu 18.04.4 LTS. My system's information is as below (via uname -a) `Linux myname 5.3.0-28-generic #30~18.04.1-Ubuntu SMP Fri Jan 17 06:14:09 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux` I could Setup Locale and Setup Sources with no issue. Then, it came to Install ROS 2 packages. Running sudo apt update gave me: Hit:1 http://archive.ubuntu.com/ubuntu bionic InRelease Hit:2 http://archive.canonical.com/ubuntu bionic InRelease Hit:3 http://archive.ubuntu.com/ubuntu bionic-updates InRelease Hit:4 http://archive.ubuntu.com/ubuntu bionic-backports InRelease Hit:5 http://packages.ros.org/ros2/ubuntu bionic InRelease Hit:6 http://archive.ubuntu.com/ubuntu bionic-security InRelease Reading package lists... Done Building dependency tree Reading state information... Done 234 packages can be upgraded. Run 'apt list --upgradable' to see them. N: Skipping acquire of configured file 'main/binary-i386/Packages' as repository 'http://packages.ros.org/ros2/ubuntu bionic InRelease' doesn't support architecture 'i386' What does the last error message mean? How do I resolve this? Then, I ran sudo apt install ros-eloquent-desktop and it returned: The following packages will be upgraded: cpp-7 g++-7 gcc-7 gcc-7-base libasan4 libcilkrts5 libdrm-amdgpu1 libdrm-common libdrm-intel1 libdrm-nouveau2 libdrm-radeon1 libdrm2 libexif12 libgcc-7-dev libglib2.0-0 libglib2.0-bin libicu60 libjpeg-turbo8 libjson-c3 libopenexr22 libpython2.7 libpython2.7-minimal libpython2.7-stdlib libpython3.6 libpython3.6-minimal libpython3.6-stdlib libsqlite3-0 libssl1.1 libstdc++-7-dev libubsan0 libuuid1 libwayland-client0 libwayland-cursor0 libwayland-egl1 libwayland-server0 libxml2 python3.6 python3.6-minimal 38 upgraded, 881 newly installed, 0 to remove and 196 not upgraded.

[Y/n] y Ign:1 http://archive.ubuntu.com/ubuntu bionic-updates/main amd64 gcc-7 amd64 7.5.0-3ubuntu1~18.04 Err:1 http://archive.ubuntu.com/ubuntu bionic-updates/main amd64 gcc-7 amd64 7.5.0-3ubuntu1~18.04 Connection failed [IP: 91.189.88.152 80] E: Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/g/gcc-7/gcc-7_7.5.0-3ubuntu1~18.04_amd64.deb Connection failed [IP: 91.189.88.152 80] E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing? I truncated the response to only keep the last part which I think will help you to know what's wrong. I googled but could not find the solution. I don't have any firewall and antivirus installed as well. Please help. Thanks a lot.
2021-05-26 15:40:28 -0500	marked best answer	colcon build failed for soss-ros1 in soss I followed steps in https://github.com/osrf/soss to run the demo for understanding of SOSS. I have installed both ROS Crystal and Melodic. However, `colcon build` failed for building `soss-ros1` . I attach the logs. I am unsure what those error messages mean. Can you please help to take a look? Thanks.
