我最近买了一台二手 Nexus 5X，它已经 root 了，并且安装了 Lineage OS。我想把它转换成 Plasma Mobile，但每次我尝试用命令刷新它时
sudo ./pm-flash
我在中途收到一条错误消息。如果有帮助的话，我会附上整个输出，但错误出现在最后。

./fetch-demo.sh: 16: ./fetch-demo.sh: pushd: not found
如果有人能帮助找出为什么它在最后一行卡住，我将不胜感激。
（如果有帮助的话，我正在运行 Linux Mint 18 Xfce。）
答案1
（注：这最初是由 OP 作为对问题的编辑发布的）。
我给 Plasma Mobile 发了一封电子邮件，得到了答复：
问题在于脚本/bin/sh使用的fetch-demo.sh链接指向/bin/dashDebian 和 Linux Mint 等衍生版本。由于 dash 不支持 pushd 支持，因此脚本崩溃。
要修复此问题，fetch-demo.sh脚本应在 Bash 中运行。我刚刚提交了一个补丁来默认修复此问题：https://github.com/plasma-phone-packaging/pm-flashtool/pull/36
如果您不想等到它被接受，请编辑第一行fetch-demo.sh从#!/bin/sh到#!/bin/bash。
