It shows this issue as fixed but I am still having this problem. after a long download and install process I am left with no program. Process finishes and poof all gone. Fairly new computer with win 10.

I had the same problem in my 2012 model iMac. now i still have the same problem with 2020 MacBook pro.

I tried everything and still can't fix the issue, I'm using Windows 8.
I tried:
1- Uninstalling old Unity versions and reinstalling Unity Hub.
2- Changing install location in Unity Hub.
3- Restarting my PC.
4- Installing the Editor only without any additions or platforms.
5- Run Unity Hub as administrator.

So far nothing worked :(

how is it marked as fixed and I still have it with 2019.3.7f1

I'm having this issue on March 16-17 2020. I read somewhere else that uninstalling and reinstalling the hub with administrator privileges can help but when I tried this the download also failed but this time I received an error message saying that the server is unresponsive.

I believe this confirms my theory that the Unity Hub is failing because of a poorly configured timeout function. If it doesn't hear back from the server for a few seconds then the download fails. This is a huge problem for busy wifi networks because they tend to get busy in spurts causing the Hub to timeout.

So, the issue is definitely not fixed, the installation of 2019.3.x version via Unity Hub 2.3.0 was just breaking up without any messages.

Workaround that helped:
1. Uninstall all current Unity Editor versions
2. Uninstall Unity Hub
3. Reinstall Unity Hub
4. Change the Unity Editors path in the Unity Hub
5. Run the installation as usual via Unity Hub

I had the same problem, but I am using linux through a chromebook, anyone know a linux fix?

same issue on 2.3.0 with Mac Catalina. Nothing is downloaded into UnityEditor folder

totally not fixed, keeps happening to me and multiple colleagues

Same problem here. I tried 2 times, I can see it downloads as my C drive space is getting lower, but it doesn't appear in the Hub.
