我最近尝试apt-get dist-upgrade -t jessie-backports安装新的 Debian Jessie。它给了我以下信息：
Err http://ftp.debian.org/debian/ jessie-backports/main dh-autoreconf all 12~bpo8+1
502 Data corruption
E: Failed to fetch http://ftp.debian.org/debian/pool/main/d/dh-autoreconf/dh-autoreconf_12~bpo8+1_all.deb 502 Data corruption
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
当我运行时apt-get dist-upgrade -t jessie-backports --fix-missing，我没有注意并注意到它计划删除大量软件包，包括 Xserver，因为以前从未发生过这种情况。当我再次尝试安装 X 时，我得到了以下信息：
The following packages have unmet dependencies:
linux-image-3.16.0-4-amd64 : Depends: initramfs-tools (>= 0.110~) but it is not installed or
linux-initramfs-tool
linux-image-4.9.0-0.bpo.2-amd64 : Depends: initramfs-tools (>= 0.120+deb8u2) but it is not installed or
linux-initramfs-tool
E: Unmet dependencies. Try using -f.
当我运行时apt-get -f install，我收到另一个错误告诉我运行apt-get autoremove，这删除了更多的软件包，但我仍然遇到相同的错误，所以我运行了apt-get install initramfs-tools。现在，当我尝试使用apt安装 X 或进行 dist-upgrade 或其他任何操作时，我得到以下信息：

尽管引用了3.16.0-4，uname -r给了我4.9.0-0.bpo.2-amd64。我尝试重新启动，认为 3.16 内核处于活动状态并且重新启动将使用 4.9，但没有运气，我遇到了相同的错误。我不知道我做了什么或如何解决它。
