证书问题

我遇到了 CA 证书问题。我尝试访问的每个网站都要求我确认证书，而且我的更新也无法 100% 正常工作

$ sudo rm -rf /etc/ssl/certs/*
$ sudo update-ca-certificates Updating certificates in /etc/ssl/certs... 152 added, 0 removed; done.
Running hooks in /etc/ca-certificates/update.d....done.
$ sudo apt-get update

你运行 时自己删除了所有证书sudo rm -rf /etc/ssl/certs/*。这会破坏您的系统。您可以采取的修复措施之一是重新安装它们来自的软件包：

sudo apt-get install --reinstall ca-certificates

这应该是相对安全的。如果这不起作用，您可能需要清除软件包并重新安装，但如果您目前有损坏的软件包，请不要尝试这样做。

sudo apt-get -f install
# stop if you saw any errors

sudo dpkg --purge --force-depends ca-certificates
sudo apt-get -f install
