Linux下安装.NET MAUI时执行dotnet workload install android报错求助

通过sudo snap install dotnet-sdk --classic安装.NET SDK 7后，执行dotnet workload install android时出现只读文件系统错误，错误日志如下：

dotnet workload install android

• 用户级安装工作负载：
  执行以下命令，将Android工作负载安装到用户目录，规避Snap包的只读限制：

  dotnet workload install android --user
  

• 替换为官方脚本安装.NET SDK：
  如果用户级安装无效，可卸载Snap版本，改用官方脚本安装：

  1. 卸载Snap版本的.NET SDK：

     sudo snap remove dotnet-sdk
     

  2. 运行官方安装脚本（以7.0.408版本为例，可替换为最新的7.x版本号）：

     curl -sSL https://dot.net/v1/dotnet-install.sh | bash /dev/stdin --version 7.0.408
     

  3. 配置环境变量：
     打开~/.bashrc或~/.zshrc文件，添加以下内容：

     export PATH="$HOME/.dotnet:$PATH"
     

     保存后执行source ~/.bashrc或source ~/.zshrc使配置生效。

• Rider中配置SDK路径：
  打开Rider的设置（File > Settings > Build, Execution, Deployment > Toolset and Build），将SDK路径指向用户目录下的.dotnet文件夹（若使用脚本安装）。
