我尝试使用sudo dpkg-reconfigure ca-certificates命令安装自签名 SSL 证书，但在完成之前，我的计算机因电源故障而重置。
现在，当我运行sudo dpkg-reconfigure ca-certificates命令时，出现以下错误：
sudo dpkg-reconfigure ca-certificates
/usr/sbin/dpkg-reconfigure: ca-certificates is broken or not fully installed
当我尝试时sudo update-ca-certificates，出现以下错误：
sudo update-ca-certificates

当我尝试 sudo 时apt install ca-certificates -f，出现以下错误：

因此，我甚至无法将我的工作推送到 Git repo。当我尝试这样做时，我收到以下错误：
fatal: unable to access 'https://github.com/***/***-tdd.git/': Problem with the SSL CA cert (path? access rights?)
有人知道如何修复这个问题吗？不用我重新安装 Ubuntu？请帮忙。
答案1
看起来 c_rehash perl 脚本中有一个错误（我遇到了类似的错误，我发现了以下讨论：https://aur.archlinux.org/packages/icaclient/?comments=all）。在我的系统（archlinux，看起来你的系统在 /usr/bin/c_rehash）上的 /bin/c_rehash 中缺少一些引号。我不得不更改这个（靠近文件顶部）：
my $dir = /etc/ssl;
my $prefix = /usr;
到：
my $dir = "/etc/ssl";
my $prefix = "/usr";
然后它就成功了。

就我而言，错误关闭 ca-certificates 设置导致文件损坏。重新安装/更新“debconf”解决了我的问题：
sudo apt-get install debconf
