我有一个无头 debian Raspberry PI，它运行Owncloud server.
apt owncloud 安装文件曾经位于此处：
http://download.owncloud.org/download/repositories/stable/Debian_8.0/
owncloud.list所以我在我的目录中创建了一个名为的文件，/etc/apt/sources.list其中包含以下内容：
德布http://download.owncloud.org/download/repositories/stable/Debian_8.0//
相应的密钥已安装在 apt 中，一切正常。
现在 owncloud 已将安装文件的位置更改为：
http://download.owncloud.org/download/repositories/product/Debian_8.0/
我已将 owncloud.list 的内容更改为：
德布http://download.owncloud.org/download/repositories/product/Debian_8.0//
并将相应的密钥添加到apt中。
一切再次正常，Owncloud 得到更新，除了当我启动系统时。然后文件的旧内容owncloud.list和旧密钥再次出现。
所以我必须手动更改 owncloud.list 并再次导入新密钥。
这里发生了什么？
我确实按照下面提到的说明进行操作。系统的状态是刚启动后。记下 owncloud.list 文件的日期。我两天前按照说明进行了编辑。那么我们开始吧：
root@RAPI2-V2:/etc/apt/sources.list.d# ls -l

-rw-r--r-- 1 root root 76 Apr 18 2016 owncloud.list
-rw-r--r-- 1 root root 193 Nov 21 2015 raspi.list

E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
运行dpkg --configure -a会删除最后一个错误，并且apt-get update不会出现错误。
这是更新后的关键内容：

现在如果我重新启动。 owncloud.list 文件恢复为旧版本，新密钥消失。
新更新：
重新启动了。当它出现时我做了：
移除钥匙
添加密钥
更改 owncloud.list
apt-get 更新
得到错误：
E: dpkg 被中断，您必须手动运行“dpkg --configure -a”来纠正问题。
dpkg --configure -a然后跑了一个
apt-get update
没有错误。
新的重启。
owncloud.list 文件已再次恢复
现在我发现问题不仅与 apt/dpkg 文件有关，根主目录在重新启动之前看起来像这样：

请注意，我已删除该Release.key文件。我把它下载到Release-new.key文件里了。现在重新启动后，主目录如下所示：

现在，文件Release-new.key已经消失了，Release.key文件也被收割了。
到底发生了什么事？看起来 SD 卡没有更新，但是如何在 syslog 或 kern.log 中没有任何错误的情况下发生这种情况？每次启动时它也会认为是 9 月 17 日。唯一可疑的消息：
Sep 17 19:17:09 RAPI2-V2 kernel: [ 5.785232] FAT-fs (mmcblk0p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
Sep 17 19:17:09 RAPI2-V2 kernel: [ 8.230865] sda: sda1
我已经运行了 fsck。没什么好抱怨的。
答案1
该问题与 apt/dpkg 无关，而是与 I/O 未写入 SD 卡有关。没有任何错误消息。显然，即使没有向卡写入任何内容，SD 卡也会报告成功的 I/O 状态。我将在 RaPi 论坛上提出问题。
