Could not detect OS (raspbian)

[christianrauch]

I am running rosdep on Raspberry Pi OS and got the following error:

ERROR: Rosdep experienced an error: Could not detect OS, tried ['zorin', 'windows', 'nixos', 'clearlinux', 'ubuntu', 'slackware', 'rocky', 'rhel', 'qnx', 'pop', 'osx', 'sailfishos', 'tizen', 'oracle', 'opensuse', 'opensuse', 'opensuse', 'opensuse', 'opensuse', 'openembedded', 'neon', 'mx', 'mint', 'linaro', 'gentoo', 'funtoo', 'freebsd', 'fedora', 'elementary', 'elementary', 'debian', 'cygwin', 'euleros', 'centos', 'manjaro', 'buildroot', 'arch', 'amazon', 'alpine', 'almalinux']
Please go to the rosdep page [1] and file a bug report with the stack trace below.

The OS 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"

The script may look for ID (raspbian, which is not in the set above) where alternatively, it should also look for ID_LIKE (debian, which is in the set above).

I ran into the same issue, this seems to be a bug in rospkg. I think it's related to this ticket https://github.com/ros-infrastructure/rospkg/issues/241

Did you ever get this set? I'm running into this issue too

[christianrauch]

You can override the OS with --os:

rosdep install --from-paths src --ignore-src -y --os=debian:bullseye

Just got the above stack trace as well. My OS version 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"

This was part of step 5 of this tutorial trying to do rosdep update

For now, I am using the following workaround as detailed in the rospkg code. The following command works export ROS_OS_OVERRIDE="debian" && rosdep update. As mentioned by @christianrauch above, Buster or Bullseye from the Raspberry PI OS are 'flavours' of debian

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.
