[EN] Troubleshooting "exec /PATH/entrypoint.sh" Docker Errors — Causes, Diagnostics, and Fixes

This guide analyzes common Docker startup failures like "no such file or directory" or "permission denied" involving "entrypoint.sh". Key causes include CRLF line endings, missing execution bits, incorrect shebangs, and architecture mismatches. It provides diagnostic steps (e.g., "sed -n l") and fixes such as using ".gitattributes" for LF normalization, applying "sed -i 's/\r$//'" in Dockerfiles to avoid extra packages, and handling archived Debian repositories (e.g., "node:10-buster") for legacy builds.
