Fixing 'exec format error' in a container
Checks the image's recorded architecture against the host's before assuming a CPU mismatch, fixes it with a multi-arch build, and verifies. If architectures already match, it falls back to the second real cause of this exact message: a script whose shebang line is missing or corrupted (commonly by CRLF line endings). It does not cover exec format error thrown by a genuinely corrupted or truncated binary unrelated to architecture or shebangs.
