If you do not use Docker and run a release or build artifact directly, browser scripts, screenshots, and chromedp tasks depend on the host for Chromium language packs, CJK fonts, and the zh_CN.UTF-8 locale.
The Docker image already includes the common runtime environment. Use this page only when you run autClaw directly on the host and screenshots, browser scripts, or rendered pages show Chinese boxes, mojibake, or missing glyphs.
One-click install on Debian / Ubuntu
