How To Fix update-binfmts: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu update-binfmts is provided by binfmt-support package.

binfmt-support is:

The binfmt_misc kernel module, contained in versions 2.1.43 and later of the Linux kernel, allows system administrators to register interpreters for various binary formats based on a magic number or their file extension, and cause the appropriate interpreter to be invoked whenever a matching file is executed. Think of it as a more flexible version of the #! executable interpreter mechanism.

This package provides an ‘update-binfmts’ script with which package maintainers can register interpreters to be used with this module without having to worry about writing their own init.d scripts, and which sysadmins can use for a slightly higher-level interface to this module.

sudo apt-get -y install binfmt-support

This command might take some time to finish depending on your machine internet connection.
