从 Raspbian 7 升级到 Raspbian 8 时出现了一些问题。我找到了与此标题相似的线程，并尝试了很多方法，但我总是遇到相同的错误。
节点位于有限带宽线路上的远程位置，因此进行完全重建是不切实际的。
我得到的信息最丰富的消息是“dpkg -C”：
root@mynode# dpkg -C
The following packages are in a mess due to serious problems during
installation. They must be reinstalled for them (and any packages
that depend on them) to function properly:
libc6:armhf Embedded GNU C Library: Shared libraries
The following packages have been unpacked but not yet configured.
They must be configured using dpkg --configure or the configure
menu option in dselect for them to work:
libc6-dev:armhf GNU C Library: Development Libraries and Header Files
libc-dev-bin GNU C Library: Development binaries
locales GNU C Library: National Language (locale) data [support]
libnih1 NIH Utility Library
libnih-dbus1 NIH D-Bus Bindings Library
但是当我尝试安装或重新安装 libc6:armhf 时，会发生这种情况：
root@mynode# apt-get --reinstall install libc6:armhf
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
locales : Depends: libc-bin (> 2.19) but 2.13-38+rpi2+deb7u8 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
当我尝试安装或重新安装 libc-bin 时，我得到：
root@mynode# apt-get --reinstall install libc-bin
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following extra packages will be installed:
libc6
Suggested packages:
glibc-doc
The following packages will be upgraded:
libc-bin libc6

我被困住了。有什么建议么？
答案1
我想通了 - 有点 - 我发现了一个相同的系统，能够在出现问题时进行升级。我比较了 /etc/apt 中的各个文件，发现了许多差异。
我将整个 apt 目录从成功的系统复制到损坏的系统，这解决了问题。
祝任何试图找出正确文件内容的人好运。谷歌搜索会返回 1000 个答案，每个答案都不同。对我来说幸运的是我有一个正确的系统。所以这里有另一种配置供您尝试。这个对我来说适用于五个不同的系统：
/etc/apt/sources.list：
deb http://archive.raspberrypi.org/debian/ jessie main
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
#deb-src http://archive.raspberrypi.org/debian/ jessie main
root@stn4133:/etc/apt# more sources.list
deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
#deb-src http://mirror.ox.ac.uk/sites/archive.raspbian.org/archive/raspbian/ jessie main contrib non-free rpi
/apt/etc/sources.list.d/raspi.list：
deb http://archive.raspberrypi.org/debian/ jessie main
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
#deb-src http://archive.raspberrypi.org/debian/ jessie main
您可能还会收到错误消息，告知您缺少公钥。这是因为 trust.gpg 不完整。要解决此问题，您可以按照本文中的说明进行操作： https://chrisjean.com/fix-apt-get-update-the-following-signatures-couldnt-be-verified-because-the-public-key-is-not-available/
