[JuliusHerrmann]

I want to have code completion for Unity3d but due to this error my code completion is not working:
Unable to create directory "/Debug/". Access to the path "/Debug/" is denied.

I got the same problem on Ubuntu 19.04 (disco dingo).

Omnisharp-vscode version : 1.19.1
dotnet version (installed via snap) : 2.2.300
mono version : Mono JIT compiler version 5.18.0.240 (Debian 5.18.0.240+dfsg-2ubuntu2 Wed Apr 17 23:39:09 UTC 2019)

[Eyap53]

Upgrading Mono from 5.18 to 5.20 solved this issue for me.

[akshita31]

@JuliusHerrmann Could you try updating mono as mentioned above and checking if the issue still persists.
You could also try setting "omnisharp.useGlobalMono": never and then restarting vscode.

Same problem with Mono JIT compiler version 6.0.0 (makepkg/f8ea05bddcb Wed 11 Sep 2019 12:21:58 AM CEST)

I use Arch btw.
