如何修复 saucy->trusty 升级挂起：“从 Mono 中删除___”

在最近从 Ubuntu 13.10 (saucy) 升级到 14.04.1 LTS (trusty) 时，该过程一直挂起，prerm并且postrm删除脚本单核细胞增多症包。问题的症状是输出中出现如下消息dpkg（/var/log/dist-upgrade/apt-term.log如果使用ubuntu-release-upgrader）：

$ egrep -B1 'Removing.+ from Mono' /var/log/dist-upgrade/apt-term.log

该过程挂在以下软件包的prerm和脚本上：postrm

为了强制删除软件包，我确定了挂起的prerm和postrm脚本，手动运行它们，然后终止挂起的进程。在发布升级期间，我不得不多次执行此操作：

修理

  1. 找到挂起的prerm脚本postrm并手动运行它：对于挂起的包，

    eval "sudo $(ps xa -o cmd | grep 'postrm\|prerm' | grep -v grep)"

    您应该会看到类似以下内容的输出：Removing libmono-addins-gui0.2-cil from Mono
  2. 杀死挂起的prerm脚本postrm：

    ps -ef | grep 'prerm\|postrm' | grep -v grep | awk '{ print $2 }' | xargs sudo kill -9
  3. 对下一个挂起的包裹重复以下信息：Removing ___ from Mono

如果遇到错误：

在升级过程中，我遇到了postinstmono 包之一的脚本故障（mono-gac... 更像mono-gack!!）。我按照上面的初始步骤操作，但脚本除外postinst。然而，这导致我升级失败，升级实用程序处于损坏状态。

我的升级日志中的错误是（为简洁起见，已编辑...请参阅完整日志在这里)：

那么你的升级过程肯定失败了。你需要强制退出升级程序，将系统重置为之前的版本，然后重新开始升级：

  1. 如果您正在使用 GTK 版本升级程序：按 Ctrl-C 并询问Yes您是否确实要退出。

    如果仍然没有退出... 使用以下命令强制退出：

    ps -ef | grep do-release-upgrade | grep -v grep | awk '{ print $2 }' | xargs kill -9
  2. 重置您的发布（例如，我重置回saucy发布trusty）：

    sudo sed -i -e 's/trusty/saucy/' /etc/apt/sources.list

    sudo sed -i -e 's/trusty/saucy/g; s/14\.04\.1/13.10/g; s/LTS//; /etc/lsb-release

    例如，您的文件应如下所示：

DISTRIB_ID=Ubuntu DISTRIB_RELEASE=13.10 DISTRIB_CODENAME=saucy DISTRIB_DESCRIPTION="Ubuntu 13.10"

  1. 使用以下命令重新运行升级：sudo do-release-upgrade

答案2

前面的答案有一个拼写错误，它说要运行，
sudo sed -i -e 's/trusty/saucy/g; s/14.04.1/13.10/g; s/LTS//;'
但没有说要将该编辑应用到哪个文件。

我的猜测是他们的意思是 /etc/lsb-release 并且编辑该文件（以及所示的 /etc/apt/sources.list）对我有用。

PS：该网站说我没有足够的业力或其他任何东西来发布“评论”，所以发布这个“答案”（实际上是评论）是唯一的选择......

此外，这里有一个脚本，可以自动执行上一个答案中描述的重复的 ps/run-by-hand/kill 过程（根据需要多次运行脚本以解决挂起问题）

#!/bin/sh
set -e -u
unset GREP_OPTIONS GREP_COLOR GREP_COLORS
line=$(ps xa -o pid,cmd | grep 'postrm\|prerm' | grep -v grep)
[ -n "$line" ] || { echo "No postrm/prerm cmd is running now." >&2; exit 1; }
pid=$( echo "$line" | sed -ne 's/^ *\([0-9][0-9]*\) .*/\1/p' )
cmd=$( echo "$line" | sed -ne 's/^ *[0-9][0-9]* *//p' )
eval "sudo $cmd"
echo -n "Kill pid $pid ? "
read reply
case "$reply" in
 [yY]*) (set -x; sudo kill $pid)
        && sleep 1 \
        && sudo kill $pid >/dev/null \
        && (set -x; sudo kill -9 $pid)
        ;;
esac
