Have attempted a complete removal of all elements including ~Library and reinstalling. Still get the same error

 

Unity Hub v2.4.0

I have attached some screenshots as I feel that I must be doing something incorrectly. At the end of the install, I get two instances of Unity and I'm guessing that's not what I should be getting. This was after a complete removal - again including ~/Library elements.

My guess is that I am making an error by not specifying a path for the Unity Editors Folder from the Unity Hub settings or the path definition of the project - or both.

 

I'm on Mojave using Unity Hub 2.4.2, and I had this same issue when trying to install 2021.1.0b1 (Beta).

I had two instances of "Unity.app" and "Unity Bug Reporter.app" after the install in these two locations:
- /Applications/Unity/Hub/Editor/2021.1.0b1/
- /Applications/Unity/Hub/Editor/2021.1.0b1/Unity/

I found out the "Unity.app" inside the Unity subfolder did contain "Contents/Resources/PackageManager/Server/UnityPackageManager" while the other one did not, so I simply replaced the instances outside of the subfolder with the ones in the Unity folder, and everything worked!

Hope this helps someone else =]

 

broooooo……..
you actually have the biggest brain in the world. it worked!!!!!!!!! thank you so much. I have to say you are one beast man I've been working on this unity download trash for so long and you have made my day

 

you have to tell the devs or somebody make a video I dont know but make sure other people know about this

 

Could not find UPM executable at path '/Applications/Unity/Hub/Editor/2020.3.2f1/Unity.app/Contents/Resources/PackageManager/Server/UnityPackageManager'


(Hopefully this helps search crawlers find this post, and jiheh's post above)

Thank you jiheh!

 

Same here. installing 2020.3.8f1 I opened my project and got that error. I found the 2 instances of Unity. Both appeared to have the package manager but the one in the Unity subfolder was over 6GB and the other one was only 4GB. So I moved the one from the subfolder up and overwrote the smaller Unity.app and now I can open the project. One thing though, the Unity Hub is missing the option to "Add Modules" to the installation. This will be a problem if I want to add other platform targets. So something is broken. I'm on Big Sur. I've already tried reinstalling.

 

Having same issue.... I ran a dignose and it gave me this in the diagnose file, 5 tests passed, but one resulted as unknown :
UPM health check (UNKNOWN)
Start the UPM process and call its health endpoint
>> Could not find UPM executable at path 'C:\Program Files\Unity\Hub\Editor\2020.3.9f1\Editor\Data\Resources\PackageManager\Server\UnityPackageManager.exe'

 

Please follow the process in the post above yours so we can take a look at this.

 

Just FYI, I had the same problem, with Unity 2020.3.12f1 (on macOS Big Sur 11.4) which I installed, uninstalled, reinstalled, rebooted without success. Just like @jiheh and others (but on different versions), I had two copies of Unity.app, one of which was smaller. Unity Hub 2.4.3. Works after replacing the smaller version with the bigger, but this must be an error in the installer then.

 

I just tried install latest 2020.3.18f1 and get the error

""could not find unity package manager local service application""

This is crazy

EDIT: Diagnostic says only one error

UPM health check (UNKNOWN)
Start the UPM process and call its health endpoint
>> Could not find UPM executable at path 'C:\Program Files\Unity\Hub\Editor\2020.3.18f1\Editor\Data\Resources\PackageManager\Server\UnityPackageManager.exe'

I check and there is no "server"" folder created in the PackageManager folder

 

Hi,

The software is not working, can you please provide a direct download to this server files so we can work now and then we may submit a bug, which may take months to resolve.

We need to work today, not in few weeks or months, that is the issue with submit a bug report.

EDIT: I copied the server folder from the Unity 2019.4 installation, fingers crossed it works !!!

 

Just logged in to bump this from 2022, if you're still on Catalina and were having the same issue like me, the fix mentioned above by jiheh worked.

 

Another bump from 2022.
It's 2 years since this issue reported and still not fixed =\
Got it reproduced with Hub 3.3.0 while installing 2020.3.41f1 LTS on Mac 12.6 (21G115) running in VM on my Win host PC.

Thanks @jiheh for the proper workaround.

 

you are so smart this worked perfectly thank you so much

 

f

Yep, Works perfectly!

 

I experienced this on a iMac running Ventura 13.2.1.

I noticed there was running antivirus,

• Uninstalling the broken Unity version (here 2022.3.10)
• Disable antivirus
• Reinstall Unity through Hub(3.5.2)

This fixed the issue here.

I was getting this error, quite descriptive

Code (CSharp):

1.  Could not find Unity Package Manager local server application at [/Applications/Unity/Hub/Editor/2022.3.10f1/Unity.app/Contents/Resources/PackageManager/Server/Unity PackageManager].
2. Missing files could be the result of an antivirus action or a corrupt Unity installation.

 

thank you, Jiheh. It works!!!

 

I usually don't reply to forums, BUT THIS WORKS

 

You are very smart this fixed my issue, thank you !

 

Hey all,

I'm having the same issue and don't understand how to do what your saying above.
Any help would be much appreciated.

Thanks,
Kyle,
