安装软件包和 apt-get 更新时出错

我试图安装 mariadb-server，但是在安装过程中出现错误，尝试执行 apt-get update 时也出现大致相同的错误。

这是 apt-get update 的命令输出：

我如何解决它？

答案1

检查你的 iptables 规则。你可能忘记指定洛接口和传入连接的规则：

iptables -A INPUT -i lo -j ACCEPT
iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT

答案2

您可以尝试以下操作：

sudo rm -rf /var/lib/apt/lists/* 
sudo apt-get update

这将删除现有的 apt-get 缓存并强制重新下载所有内容。如果这不能解决问题，您将需要手动浏览软件源列表并删除无效条目。

答案3

我引用了https://forums.developer.nvidia.com/t/dns-related-issues-with-custom-carrier-board-and-l4t-35-3-1/255657并且把/etc、/etc/systemd、/etc/systemd/system、/usr、/usr/lib、/usr/lib/systemd、/usr/lib/systemd/system上的大部分权限都改成了755权限。我出错的原因是，我对/root下的所有目录和文件都设置了777权限，而update对权限比较敏感，它的安全机制要求比较高，所以sudo apt-get update一直会报错。
