/bin/ash not found

This error message indicates that the shell (command-line interface) "ash" is not installed in the system's /bin directory. "ash" is a lightweight shell that is commonly used in embedded systems, but it may not be available on all systems.

To fix this error, you can try installing "ash" by using your system's package manager. For example, on Debian and Ubuntu-based systems, you can run the following command:

sudo apt-get install busybox-static

This will install the "ash" shell, as well as other basic utilities provided by the BusyBox package. If you're using a different operating system or package manager, consult the documentation for specific instructions on how to install "ash".
