hyper-v 设置 centos-9-stream dnf 更新会抛出 ssl 错误

Question

在hyper-v中安装好centos-9-stream.iso，就可以登录了。

发出

dnf update

或

dnf install java-17-openjdk-headless

时看到以下消息

$ dnf install java-17-openjdk-headless

有什么办法可以解决这个问题吗

Answer 1

至少为了我的要求，用下面的内容更新了

/etc/dnf/dnf.conf

文件

sslverify=False

现在

dnf update

可以正常工作了。另外，为了连接到互联网，更新了

/etc/resolv.conf

文件

nameserver 8.8.8.8

。
