我正在尝试构建一个基于ubuntu:20.04的 Docker 映像，其中包含 R 和支持 PDF 的 bookdown。但我正在ERROR: cannot verify yihui.org's certificate [...]接受tinytex::install_tinytex()：

You may have to restart your system after installing TinyTeX to make sure ~/bin appears in your PATH variable (https://github.com/yihui/tinytex/issues/16).

我需要找到一种方法来验证和信任来自yihui.org的证书链，因为我不允许绕过验证--no-check-certificate。

提前感谢您的任何提示！米海

默认的 docker 镜像没有安装证书，因此也没有根证书。这就是错误消息所指示的内容Unable to locally verify the issuer's authority。您可以从包中获取根证书ca-certificates（通过 安装它apt-get）。
