Ubuntu 安装中的依赖项错误

我正在尝试修复 Ubuntu 服务器中的 APT 设置，该服务器只有 SSH 访问权限，但无法找出依赖性错误。

我已经运行sudo apt-get install -f，并得到以下结果：

 ssl-cert
 postgresql-common
 postgresql-8.4
 postgresql
E: Sub-process /usr/bin/dpkg returned an error code (1)

这到底是什么意思？是否存在循环依赖？

我尝试安装所需的依赖项ssl-cert，但它也不起作用。

我也不能dpkg直接使用。

有什么方法可以解决这个问题吗？或者有人能帮我更好地理解这个问题吗？我还需要提供其他信息吗？

编辑：
运行sudo sh -x /path/to/config.postinst configure产生以下输出：

+ . /usr/share/debconf/confmodule
+ [ !  ]
+ PERL_DL_NONLAZY=1
+ export PERL_DL_NONLAZY
+ [  ]
+ exec /usr/share/debconf/frontend /var/lib/dpkg/info/ssl-cert.postinst configure

这是否意味着脚本无法执行最后一行？

运行sudo /usr/share/debconf/frontend /var/lib/dpkg/info/ssl-cert.postinst configure悄无声息地完成，但随后echo $?出现1，表明确实发生了错误。

当我添加set -x到文件顶部，然后运行命令时sudo ... frontend ... configure，它会失败：

make-ssl-cert generate-default-snakeoil

set -x此文件也失败了：

 openssl req -config /tmp/tmp.wPl6nkzKYm -new -x509 -days 3650 -nodes -out /etc/ssl/certs/ssl-cert-snakeoil.pem -keyout /etc/ssl/private/ssl-cert-snakeoil.key

运行此命令可得到sudo：

Generating a 1024 bit RSA private key

53829:error:0D07A097:asn1 encoding routines:ASN1_mbstring_ncopy:string too long:a_mbstr.c:154:maxsize=64

我不熟悉 OpenSSL；这里发生了什么事？

（此外，我应该将其分叉为一个新问题吗？这个问题的范围是否已经超出？）

答案1

我转了一圈，似乎您的“公司名称”对于 openSSL 来说太长了。这是一个错误。您应该将系统升级到精确或更高版本以解决此问题。

删除所有阻止包并升级系统。这应该可以解决问题。

答案2

输出中的关键摘录是运行ssl-cert包的安装后脚本时出现的此错误：

Setting up ssl-cert (1.0.23ubuntu2) ...
dpkg: error processing ssl-cert (--configure):
subprocess installed post-installation script returned error exit status 1

所有后续错误均是由于未能完成安装而导致的ssl-cert。

为了确切地postinst 脚本如何失败， 跑步

sudo sh -x /var/lib/dpkg/info/ssl-cert.postinst configure

一旦您成功调试了根本原因，请sudo apt-get install -f再次运行。
