HassOs , installed extra packages but still not able to use them , command not found

Hey, in HassOs i installed some extra packages for testing… I am aware that they are gone after every update, thats not an issue…

but after installing the packages , i still cant use the commands, why is that?

see example screenshot :

ok, i think whats wrong, seems those tools are not part of “cantools” , i think i need “can-utils”

how can i install that ?

omg, its just the command “apk add can-utils”
now i also need to load the module on startup hassos

“sudo modprobe slcan” any idea how todo it?
