我需要帮助
问题如下：

“检测到v2ray-core”的版本并非v5，请使用v5版本或将v2ray降级至v1.5“
v2rayA服务端正在运行，Version:2.0.5

请问谁知道怎么降级或者使用v5版本的v2ray-core

我这边使用的是raspberry pi os 32bit。

我的v2Ray 版本
V2Ray 4.28.2 (V2Fly, a community-driven edition of V2Ray.) Custom (go1.15.2 linux/arm)
A unified platform for anti-censorship.

对于这个问题我已经解决了，参考https://github.com/v2rayA/v2rayA/issues/794。
由于网络问题我只能手动安装
先下载这个安装脚本，https://github.com/v2fly/fhs-install-v2ray/blob/master/install-release.sh
然后去https://github.com/v2fly/v2ray-core/releases，下载对应的包我需要的是[v2ray-linux-arm32-v7a.zip](url)

然后参考https://dsencheng.github.io/15936838298753.html

先卸载
sudo bash install-release.sh --remove
sudo apt purge curl unzip

再手动安装
sudo bash install-release.sh --local v2ray-linux-arm32-v7a.zip
启动
sudo systemctl start v2ray
sudo systemctl status v2ray

虽然没有报错然而好像并没有什么用，使用我的订阅链接我并没有翻出去
我很肯定我的梯子可以使用，他在windows和ubuntu下运行的很好，有没有大佬知道怎没解决

还没有尝试降回1.5版本之后再测试一下。

如果你是ubuntu的话 可以直接使用sudo apt-get remove v2ray先移除旧版本 然后使用sudo apt-get install v2ray=5.10.1下载回来 当然这个5.10.1是使用apt-cache madison先看v5现在哪一个可以下载的 根据实际情况来
