Unable to locate package ros-humble-desktop and ros-humble-ros-base

I followed these instructions to try and install the ros

I typed the command sudo apt install ros-humble-desktop and get a unable to locate package error. Same thing happens if I do sudo apt install ros-humble-ros-base.

Which Ubuntu are you using? Maybe It is not compatible with your os.

@KozhaAkhmet I am using 22.04. It is compatible I already checked.

The screenshot shows you're running 22.04 on an ARMhf platform (please try not to post screenshots of terminals, but copy-paste the text).

Only Ubuntu on ARMv8 gets .deb packages.

See also REP 2000: ROS 2 Releases and Target Platforms: Humble Hawksbill (May 2022 - May 2027) (ARMv8 is called arm64 in that document).

PS: I'd recommend posting these kinds of questions on robotics.stackexchange.com in the future, as this is not an issue with ROS 2 itself, and this issue tracker is reserved for actual issues.

@gavanderhoorn I have posted this on robotics.stackexchange.com. No body has responded to it.

[gavanderhoorn]

Pedantic, but cross-posting to this issue tracker without mentioning your previous posting is then also not very nice.

(but I'm not a maintainer here, so take this as my personal opinion)

Edit: is unable to locate package ros-humble-desktop ubuntu 22.04 your post? That was posted only 8 hours ago.

It was my platform that was causing the error. I could not install the ros2 with the platform I had armhf. So I ended up re flashing the sd card with ubuntu 20.04.
