我问过堆栈溢出但被重定向到这里。
我担心我犯了某种错误。
在执行升级时apt-get upgrade（队列中有大约 160 多个软件包），我意外退出，导致升级中途中止。现在我无法重新启动升级。
apt-get upgrade说没有要升级的软件包...
apt-get update给出错误：
W: Failed to fetch http://security.debian.org/dists/wheezy/updates/main/binary-armel/Packages Hash Sum mismatch
W: Failed to fetch http://security.debian.org/dists/wheezy/updates/contrib/binary-armel/Packages Hash Sum mismatch
W: Failed to fetch http://security.debian.org/dists/wheezy/updates/non-free/binary-armel/Packages Hash Sum mismatch
[several more of these... and ending in: ]
E: Some index files failed to download. They have been ignored, or old ones used instead.
E: Couldn't rebuild package cache
完整输出为在 pastebin 上
我尝试了这些但没有成功：
apt-get -f install
输出：
Reading package lists... Done
Building dependency tree
Reading state information... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
dpkg --configure -a
无输出
rm -vf /var/lib/apt/lists/*; rm -vf /var/lib/apt/lists/partial/*; apt-get update
与上面相同的错误。
dpkg-reconfigure -a
最终在此之后中止：

dpkg-query: error: --status needs a valid package name but 'gcc-4.7-base' is not: ambiguous package name 'gcc-4.7-base' with more than one installed instance
Use --help for help about querying packages.
/usr/sbin/dpkg-reconfigure: gcc-4.7-base is not installed
我不知道如何找出已安装的内容和未安装的内容。
非常欢迎任何有关如何恢复的建议！

这可能应该移至超级用户或类似用户，但由于您已经被重新重定向......
首先我建议在屏幕会话。这样，当您注销或连接中断时，更新仍会继续进行：
screen -S upd
要分离会话，请按Ctrl 一个然后按d
要重新连接会话类型：
screen -r upd
粘贴您列出的尝试过但没有成功的操作的输出也会很有帮助。
一些建议：
- 你试过切换存储库
- 你是否递归删除/var/lib/apt/列表/*
- 你是否mkdir /var/lib/apt/lists/partial
编辑：根据您添加的信息判断，您可能需要强制删除gcc-4.7-基础然后重新安装并重复dpkg-重新配置-a。如果另一个包失败，请重复此过程直至成功，然后重新运行 apt-get (dist-)upgrade。
