SSL：没有替代证书使用者名称匹配 | 新发布的CURL(USN-6237-1)带来痛苦

Question

自从 CURL https://ubuntu.com/security/notices/USN-6237-1新版本发布以来，我们在 Ubuntu 上遇到了curl命令的问题：

sudo apt update -y && sudo apt install --no-install-recommends -y curl
curl -vvv https://downloads.apache.org/maven/maven-3/3.8.8/binaries/

错误：

如何修复它？我们现在应该以某种方式控制第三方证书吗？昨天工作过。提前致谢

看起来有一个损坏的向后端口用于安全修复。应该在 7.81.0-1ubuntu1.13 中修复，该版本修复了 7.81.0-1ubuntu1.11。来自https://launchpad.net/ubuntu/jammy/+source/curl/+changelog：

获取旧版本的方法：

删除它并用于apt安装以前的版本。以下是 AU 上最活跃的主题：How to downgrade a package via apt-get? 也可以从源安装。这可能是一种更好的方法：您可以保留 apt 版本不变，等待更新/错误修复，然后在源安装版本旁边尝试新版本。

检查这些是否可以解决您的问题。如果是这样，请提交错误报告。如果你想坚持使用旧的 apt 版本，请固定包

这是一个已确认的错误：https ://bugs.launchpad.net/ubuntu/+source/curl/+bug/2028170

他们已经通过恢复更改修复了该问题，新的软件包版本很快就会上线。
