错误：ca-certificates 已损坏或未完全安装

Question

我试图用sudo dpkg-reconfigure ca-certificates命令安装自签名 SSL 证书，但在它完成之前，我的计算机由于电源故障而被重置。

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
Updating certificates in /etc/ssl/certs...
Unknown regexp modifier "/b" at /usr/bin/c_rehash line 15, at end of line
Unknown regexp modifier "/W" at /usr/bin/c_rehash line 26, at end of line

  (Might be a runaway multi-line // string starting on line 26)
syntax error at /usr/bin/c_rehash line 58, near "Prefix our installdir"
Execution of /usr/bin/c_rehash aborted due to compilation errors.

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

sudo apt install ca-certificates -f

因此，我什至无法将我的工作推送到 Git 存储库。当我尝试这样做时出现以下错误：

fatal: unable to access 'https://github.com/***/***-tdd.git/': Problem with the SSL CA cert (path? access rights?)

有谁知道如何解决这个问题而我不必重新安装 Ubuntu？请帮忙。

就我而言，错误关闭 ca 证书设置会导致文件损坏。重新安装/更新“debconf”解决了我的问题：

sudo apt-get install debconf
