apt-get 分段错误（libapt-pkg 分段错误）

从今天早上开始，我就无法运行 apt-get，也不知道为什么。这是我目前所做的：

# apt-get update
(updating list)
Fetched 2.797 kB in 7s (363 kB/s)

分段错误... 33%

# apt-get install firefox (just a random app, same outcome to all)
Reading package lists.. 33%

分段错误... 33%

尝试过：

# rm -rf /var/cache/apt
# rm -rf /var/log/apt

和

# dpkg-reconfigure libapt-pkg4.12

有什么想法吗？谢谢！

我在 Precise 中也遇到了同样的问题。为了解决这个问题，我添加了一个/etc/apt/apt.conf.d/00bugs包含一行的文件：

APT::Cache-start    200000000;

分段错误不再发生。我已针对此问题提交了错误报告： https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1445436
