How do I resolve an error when attempting the "opam init" command?

Question

Here is the command:

    opam init

Here is the error I am getting:

    bash: /use/local/bin/opam: cannot execute binary file: Exec format error

Are there any suggestions on what we should try?

Answer 1

It seems like you are trying to execute a program that might not be a valid Linux binary; a quick search for this error online will return many sites explaining how to solve it, like these:

• bash: ./program: cannot execute binary file: Exec format error
• https://superuser.com/questions/800019/unable-to-execute-binary-file-exec-format-error
• https://appuals.com/fix-cannot-execute-binary-file-exec-format-error-ubuntu/

Check if the program you're trying to execute is compatible with your Linux kernel version, like these sites I linked suggest.

However, before actually doing this, I'd try changing that path to /usr/local/bin/opam, it also looks like you might have a typo in there (usually in Linux that folder is called usr, not use).
