denesh-globotix commented 2 years ago

I have been trying to install ROS on a Raspberry PI 4 using the bullseye Raspberry PI OS version. However the following error keeps popping up:

rosdep version: 0.21.0

The operating system I am using is:

```$ cat /etc/os-release 
PRETTY_NAME="Raspbian GNU/Linux 11 (bullseye)"
NAME="Raspbian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye
ID=raspbian
ID_LIKE=debian
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

A temporary fix in the form of this has been implemented but I would like to clarify if this is the correct way to rectify the issue.

https://github.com/ros-infrastructure/rospkg/pull/244 detects Raspbian distinct from Debian and https://github.com/ros-infrastructure/rosdep/pull/867 has rosdep treat Raspbian as Debian (although that may have to change in the future as they diverge further).
