can't install snap ros package

edit

I just build and published ros2 packages in snap repo with the hlep of github action without any error. Here is the link just for testing. But now when i install the package 'turtlebot' in my raspberry pi with arm64 architecture and desktop amd64 system. Both is showing same error:

/bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
Package 'turtlebot3_navigation2' not found: "package 'turtlebot3_navigation2' not found, searching: ['/snap/turtlebot/5/opt/ros/foxy']"
