Why does a container fail with exec format error on another machine?

Step-by-step guidance
The executable or image may target a different CPU architecture, or an entry script may have an invalid interpreter format. The message alone does not distinguish them.
Inspect image platform and binary architecture, then build for supported targets with the appropriate multi-platform workflow. Check shebang and line endings for scripts. Test the actual target architecture where possible; emulation has performance and compatibility limits. Do not copy native dependencies from an unrelated host into the runtime image. A successful build on one laptop does not establish that the artifact runs on every deployment platform.
