关于pipes-and-rust安装脚本运行停滞的技术求助

这个pipes-and-rust安装脚本由第三方编写，基于HTML、Rust、Shell实现，用于通过终端向reMarkable设备安装软件，但运行时出现停滞，相关日志如下：

[main 2023-03-14T04:14:22.384Z] update#setState idle
[main 2023-03-14T04:14:23.064Z] [UtilityProcess id: 1, type: extensionHost, pid: <none>]: creating new...

[main 2023-03-14T04:14:23.076Z] [UtilityProcess id: 1, type: extensionHost, pid: 22148]: successfully created

[main 2023-03-14T04:14:52.400Z] update#setState checking for updates

[main 2023-03-14T04:14:52.425Z] update#setState idle

[8152:0313/211622.415:ERROR:gpu_init.cc(481)] Passthrough is not supported, GL is disabled, ANGLE is

脚本源码如下：

#!/usr/bin/env sh

# Set hostname or ip address of your reMarkable
host="remarkable"
port="22"


echo "Creating /opt/ directory, if it doesn't exist, yet.."
ssh "$host" "mkdir -p /opt/" || exit 1
echo "Done"

echo "Stopping previous version, if it exists..."
ssh "$host" "systemctl stop pipes-and-rust.service"
ssh "$host" "killall pipes-and-rust"
echo "Done"

echo "Copying files to device..."
scp "./pipes-and-rust" "$host:/opt/pipes-and-rust" || exit 1
sed "s/PORT=80/PORT=${port}/" -i "./pipes-and-rust.service"
scp "./pipes-and-rust.service" "$host:/lib/systemd/system/pipes-and-rust.service" || exit 1
echo "Done"

echo "Installing service..."
ssh "$host" "systemctl daemon-reload" || exit 1
ssh "$host" "systemctl enable pipes-and-rust.service" || exit 1
ssh "$host" "systemctl start pipes-and-rust.service" || exit 1
echo "Done"

echo
echo "pipes-and-rust has been successfully installed on your device!"

已尝试通过VS Code修改脚本变量，但无效果，求问题定位。

排查方向 #

1. 日志无关内容排除：日志里的VS Code更新日志和GPU错误与脚本运行无关，停滞原因集中在SSH/SCP网络交互环节
2. 主机名解析问题：默认host="remarkable"，检查本地DNS能否解析该主机名，不行则替换为reMarkable设备的实际IP地址
3. SSH连接验证：手动执行ssh [主机名/IP]，确认是否能正常登录，排查密码/密钥验证、网络连通性问题
4. SCP传输测试：手动执行scp ./pipes-and-rust [主机名/IP]:/opt/pipes-and-rust，验证文件传输是否正常，排除权限或网络阻塞问题
5. 脚本端口变量误用：脚本中port变量仅用于替换服务端口，但如果reMarkable的SSH端口不是默认22，需在所有ssh/scp命令中添加-p $port参数（例如ssh -p $port "$host" "命令"）
6. 本地文件检查：确认当前目录下存在pipes-and-rust和pipes-and-rust.service文件，避免因文件缺失导致脚本异常
