我从Windows 10迁移到Ubuntu 19.04，并且过去有一些Unity项目可以进行。我从Microsoft网站，C＃和Unity Debugger扩展，.NET SDK 2.2，最新的Mono（6.0.0.319）和Unity 2019.2.0f1安装了VS Code。当我尝试打开项目时，OmniSharp日志显示：
[warn]: OmniSharp.MSBuild.ProjectLoader Unable to create directory "/Debug/". Access to the path "/Debug/" is denied.
以及由此导致的其他一些错误，这些错误会导致无法加载.csproj文件。
首先，我已经搜索了这个问题，但是发现只有一个合适的线程说我需要重新安装msbuild。但是APT上没有任何msbuild软件包，所以我去了MSBuild的GitHub，它说msbuild并不是与.NET SDK分开提供的。
然后我卸载了Mono，但是VSC说我没有“ .NET Framework 4.7.1”，因此我再次安装了Mono。
后来我重新安装了.NET SDK和VS Code，但问题似乎仍然存在。
这是我的dotnet --info，如果它可以帮助解决：
