屏幕终止后恢复 do-release-upgrade

Question

当我的键盘出现问题时，我只是在查看我和维护者版本更改的配置差异，因为发生了以下错误：

Configuration file '/etc/bind/named.conf.options'
 ==> File on system created by you or by a script.
 ==> File also in package provided by package maintainer.
   What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : start a shell to examine the situation
 The default action is to keep your current version.
*** named.conf.options (Y/I/N/O/D/Z) [default=N] ? -- 0:bionic -- time-stamp -- Jan/09/20 11:52:04 --
-- 0:bionic -- time-stamp -- Jan/09/20 11:56:29 --

我试图重新连接到屏幕，但sudo screen -r说There is no screen to be resumed.，并sudo screen -ls说No Sockets found in /run/screen/S-root.。

我正在寻找并找到有关恢复升级的答案，但它们要么适用于仅屏幕分离的情况，要么适用于 dpkg 退出的情况。但我看到 dpkg 仍在进程列表中运行，因此以某种方式继续可能是更明智的做法。有任何想法吗？

我在这里发现了同样的情况： https: //bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1343737，同时试图找到解决方案以某种方式窃取正在运行的 dpkg\'s pty。

我能够dpkg通过继续该过程reptyer！

• 我reptyer手动下载了 deb 文件。它可以在这里找到https://ubuntu.pkgs.org/18.04/ubuntu-universe-amd64/reptyr_0.6.2-1.2_amd64.deb.html并用于wget http://archive.ubuntu.com/ubuntu/pool/universe/r/reptyr/reptyr_0.6.2-1.2_amd64.deb下载 deb 文件。

• 我从中提取了二进制文件，因为 dpkg 文件仍然通过运行dpkg. 这是使用完成的ar x reptyr_0.6.2-1.2_amd64.deb

• 在里面，data.tar.gz 被提取，然后在新usr/bin文件夹中有一个名为 的文件reptyer。

• 更改权限以允许执行该文件，sudo chmod +x reptyer

• 最后使用命令附加到设置reptyer -T <pid of dpkg>，可以使用 找到 pid htop，并搜索 dpkg 进程。瞧\xc3\xa1！:) 我再次进入升级会话并能够继续！
