我的 Ubuntu 图形输出坏了，我不得不重新安装它。为了保留我的数据和设置，我只是从 CD 上在旧系统上重新安装了它。一切都很顺利，除了每次更新都会出现错误：

stan@stan-ThinkPad-T530:/var/lib/dpkg/info$ sudo apt-get autoremove
Reading package lists... Done
Building dependency tree       
Reading state information... Done
0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
1 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.
Setting up fontconfig (2.11.1-0ubuntu6) ...
Regenerating fonts cache... failed.
See /var/log/fontconfig.log for more information.
dpkg: error processing package fontconfig (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 fontconfig
E: Sub-process /usr/bin/dpkg returned an error code (1)

有两个问题（可能相关？）困扰着我：

  1. 1 not fully installed or removed.在第 6 行。它没有告诉我哪个包没有完全安装或删除，而且我不知道如何找出它。

  2. fontconfig最后一行引起的错误。每次更新后我都会收到此错误，因为fontconfig每次运行。

cat /var/log/fontconfig.log给出以下内容：

/usr/share/fonts: caching, new cache contents: 0 fonts, 4 dirs

... a lot of lines with various fonts ...

/usr/share/fonts/type1/gsfonts: caching, new cache contents: 35 fonts, 0 dirs
/usr/share/fonts/type1/mathml: caching, new cache contents: 1 fonts, 0 dirs
/usr/local/share/fonts: caching, new cache contents: 0 fonts, 0 dirs
/.local/share/fonts: skipping, no such directory
Re-scanning /usr/share/fonts: fc-cache: symbol lookup error: fc-cache: undefined symbol: FcDirCacheRescan

我已经花了很多时间寻找可能的解决方案，并尝试了下面这些建议的命令，以及其他命令

sudo dpkg --configure -a
sudo apt-get clean
sudo apt-get dist-upgrade

但一切都是徒劳。任何调试帮助都将不胜感激！

Shutupshare 建议这样做apt-get install --reinstall libfontconfig1 libfontconfig1-dev libfontconfig1-dbg，结果如下：

stan@stan-ThinkPad-T530:~$ sudo apt-get install --reinstall libfontconfig1 
libfontconfig1-dev libfontconfig1-dbg

输出dpkg --get-selections：

1）hold（什么也没给出）

stan@stan-ThinkPad-T530:~$ sudo dpkg --get-selections | grep hold

2）purge

stan@stan-ThinkPad-T530:~$ sudo dpkg --get-selections|grep purge
rsyslog                     purge

3）deinstall

stan@stan-ThinkPad-T530:~$ sudo dpkg --get-selections|grep deinstall

其余的都有地位installed。

答案1

我也遇到了这个问题，最后用这个帖子中的 Bachstelze 答案解决了它 -http://ubuntuforums.org/showthread.php?t=1556880- 但只能使用 purge fontconfig-config 包重新安装。

这是对我有用的命令：

sudo apt-get install --reinstall --purge fontconfig-config

答案2

这是对我有用的命令： https://launchpad.net/ubuntu/trusty/amd64/libfontconfig1-dev/2.11.0-0ubuntu4.1

wget http://launchpadlibrarian.net/177041650/libfontconfig1-dev_2.11.0-0ubuntu4.1_amd64.deb
sudo apt-get install libexpat1-dev
sudo dpkg -i libfontconfig1-dev_2.11.0-0ubuntu4.1_amd64.deb

答案3

看来您遇到的主要问题是 fontconfig-config 的版本是 2.11.0-0ubuntu4.1，但安装 libfontconfig1-dev 需要 2.11.0-0ubuntu4。希望您已经解决了这个问题。如果没有，您可以尝试将 fontconfig-config 降级到 2.11.0-0ubuntu4。

sudo apt-get install fontconfig-config=2.11.0-0ubuntu4

然后，您至少可以安装 libfontconfig1-dev 以及 libfontfig1=2.11.0-0ubuntu4。

答案4

我必须跑：

apt-get remove libfontconfig1

其次是

apt-get install libfontconfig1-dev
