您能帮我解决这个问题吗？我无法继续，因为默认的 nodejs 是 10.19，它不受支持且不受维护。我遇到了这个版本的问题，现在无法将其升级到当前版本。
答案1
应当指出的是精确的表示 Ubuntu Precise Pangolin 12.04 LTS 于 2012 年 4 月发布，因此它是 EOL。
因此，您必须手动编辑您的/etc/apt/sources.list文件（或来自的其他*.list文件），并通过在行开头添加/etc/apt/sources.list.d/来注释掉行。precise-oem-sp1#
然后运行sudo apt-get update，确保此操作期间没有错误，最后继续 NodeJS 安装。
