從 Raspbian 7 升級到 Raspbian 8 時出現問題。
節點位於有限頻寬線路上的遠端位置，因此進行完全重建是不切實際的。
我得到的資訊最豐富的消息是「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
但是當我嘗試安裝或重新安裝 libc6:armhf 時，會發生這種情況：
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).
當我嘗試安裝或重新安裝 libc-bin 時，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。有什麼建議麼？
答案1
我想通了 - 有點 - 我發現了一個相同的系統，能夠在出現問題時進行升級。我比較了 /etc/apt 中的各個文件，發現了許多差異。
我將整個 apt 目錄從成功的系統複製到損壞的系統，這解決了問題。
祝任何試圖找出正確文件內容的人好運。谷歌搜尋會返回 1000 個答案，每個答案都不同。對我來說幸運的是我有一個正確的系統。所以這裡有另一種配置供您嘗試。這個在五個不同的系統上為我工作：
/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
您也可能會收到錯誤訊息，告知您缺少公鑰。這是因為 trust.gpg 不完整。要解決此問題，您可以按照本文中的說明進行操作： https://chrisjean.com/fix-apt-get-update-the-following-signatures-couldnt-be-verified-because-the-public-key-is-not-available/
