Unity Multiplayer MLAPI wont download into assets!

I downloaded git last week in preparation or this, I setup the login page with playfabs and dealt with email authentication with unity.transport and smtp I finished setting up a "gameEngine" planel with a client,server,player tab. I finally got to my scene "PlayerWorkLab" which is the first place you should spawn.

So, I need to build the player networking prefab and went to go download MLAPI today. (Before you ask/assume YES git is up-to-date 2.33/Restarted laptop for stupid windows update 4 days ago "yay audio drivers now not working right" !Thanks bill gates!)

However, it won't install. I get these two errors when downloading from the github link,"https://github.com/Unity-Technologi...th=/com.unity.multiplayer.mlapi#release/0.1.0"

error 1:
[Package Manager Window] Cannot perform upm operation: EBUSY: resource busy or locked, rmdir 'C:\Users\keola\OneDrive\Desktop\SolChroniclesInfinite\Library\PackageCache\.tmp20724Yz9gcslN85k6\clone' [NotFound].

error 2:

I am using the latest version of unity 2021 so, I'd very much like a solution to this issue asap.
I have photon in "My Assets" but, not in the project I'm working on. If that helps at all.

 

The link is broken! At the moment the url is glitched. Open the github link in your browser and download the package by name!

com.unity.multiplayer.mlapi

 

I ended up downloading the latest package as a tarball from the official repo.

https://github.com/Unity-Technologies/com.unity.multiplayer.docs/issues/306

Edit: the link seems to be working fine (except in some cases- newer Windows 10/some Win10 set-up). Thanks @Brach_Unity!

 

Try changing the settings for the Git for Windows options to old (not selecting any of the New! options). This fixed it for me.

 

So, I had exactly this problem so I tried to download and add the tarball from https://github.com/Unity-Technologies/com.unity.netcode.gameobjects/archive/refs/tags/0.1.0.tar.gz. Got the file ok, but both Unity 2020.3.0f1 or Unity 2021.1.23.f1 errored.

So then manually extracted the folder com.unity.multiplayer.mlapi from the tgz file and added it to the manifest locally: "com.unity.multiplayer.mlapi": "file:d:/_projects/Unity/Packages/com.unity.multiplayer.mlapi"

I know this won't pick up updates but it works and hopefully it will be on the main registry soon?
