包预安装脚本子进程返回错误退出状态 1

我有类似的问题 dpkg：新的预安装脚本返回错误退出状态 1

尝试安装 PacketTracer 7.3.1 时遇到与上述相同的错误。我想我拒绝了 EULA。我对 bash 和 debconf 一无所知。有谁知道如何修改这个脚本？

#!/bin/sh -e


# Source debconf library.
. /usr/share/debconf/confmodule

remove_pt ()
{
if [ -e /opt/pt ]; then
  echo "Removing old version of Packet Tracer from /opt/pt"
  sudo rm -rf /opt/pt
  sudo rm -rf /usr/share/applications/cisco-pt7.desktop
  sudo rm -rf /usr/share/applications/cisco-ptsa7.desktop
  sudo rm -rf /usr/share/icons/hicolor/48x48/apps/pt7.png
fi
}




db_fset PacketTracer_731_amd64/show-eula seen false
db_fset PacketTracer_731_amd64/accept-eula seen false
STATE=1 
while [ "$STATE" != 0 -a "$STATE" != 4 ]; do
    case "$STATE" in
    1)
        db_input critical PacketTracer_731_amd64/show-eula || true
    ;;
    2)
        db_input critical PacketTracer_731_amd64/accept-eula || true
    ;;
    3)
        db_get PacketTracer_731_amd64/accept-eula
        if [ "$RET" = "false" ]; then
            exit 1
        fi
    ;;
    esac

    if db_go; then
        STATE=$(($STATE + 1))
    else
        STATE=$(($STATE - 1))
    fi
done

这是我将 set -x 添加到 preinst 脚本并尝试安装数据包后得到的结果。

要修复 EULA 选择，您可以直接更改存储在数据库中的值debconf：

debconf-get-selections |
grep PacketTracer_731_amd64/accept-eula |
sed s/false/true/ |
sudo debconf-set-selections

然后配置待处理的包：

sudo dpkg-reconfigure --pending
