Failed to start Unity Package Manager

1st: Install 2018.2.0b1
2nd: Create New Project
3rd: I got this screenshot.

 

I re-tried to open the project about five times.
I got this dialog message few minuet later.

Continue it, Unity was opened but I got the message.
This is same as 2018.1.0b13...

 

Hi Pascal,

I tested 2017.3.1p4 but Package Manager was crashed... case 1028247
I think this crash is same as 2017.4.0f1 and 2017.4.1f1.
An workaround "Run as administrator" has not effect.
And I tried to turn off the ESET but I got same crash dialog.

I tested another version of path release.

2017.3.1p1 is OK!!
2017.3.1p2 is OK!!
2017.3.1p3 is NG!!


Thanks,
Hirokazu

 

Hi LeonhardP

I reported the problem.
case 1028272

Thanks,
Hirokazu

 

Hi Pascal,

There is no UNITY_NOPROXY environment.
There are http_proxy and https_proxy environments for our proxy.

BTY,

I found that they have same problem.

Hi Pascal,

Here are the log file.

Hello @iriguchi,

I'm very sorry you're running into all these issues while attempting to start Unity. We have attempted to reproduce the issue using the versions that have failed and were unfortunately unsuccessful. If I could ask more details from you, this could inch us closer to a potential cause and resolution.

• Would you try starting Unity without a network connection and let me know if you are able to start Unity with your project?
  • If the step above fails, could you try to start a new project with the same conditions mentioned above and let me know if that works?
• Would you please paste the following URL on your browser "https://public-cdn.cloud.unity3d.com/config/production" and let me know what the response is?
  • It should look like this: https://imgur.com/a/51xxxQj

Ultimately, please confirm the following for me:

• Node is not blocked at the firewall level
• No antivirus is running on your machine. If there is one active, it doesn't block Unity processes.
• Under the location where your executable lies Path to your executable (in my case == C:\Program Files\Unity 2017.3.0a1) \Editor\Data\Resources\PackageManager\Editor please confirm that there are .tgz files in there like this: https://imgur.com/a/HHc2hXC

Thank you so much for your help and please accept my sincere apologies for the issues you're running into.

Hi Pascal and Pedro,

I fixed this problem with your advice.
Thank you for your support.

I found the mistake HTTPS_PROXY environment setting.

Like this.
export HTTP_PROXY="http://host:portnumber"
export HTTPS_PROXY="https://host:portnumber"

I typo "https".
I fixed it to "http", The Package Manager works fine.
.
I guess the package manager change the environment to use form HTTP_PROXY to HTTPS_PROXY
at the version 2017.3.1p3.

Thanks again.
Hirokazu

 

Thank you @iriguchi,

We didn't notice the typo on our end either. I'm so glad the situation has resolved itself. I will investigate what happened on version 2017.3.1p3.

And finally, Hirozaku, thank you for your patience as you worked with us in getting the problem addressed. It is thoroughly appreciated!

@pedro_unity
I had the same problem with 2018.1 and one of your QA guys was able to reproduce the issue, I thought it was fixed.
I'll look up the case.

 

Thank you @xCyborg!

@pedro_unity I'm still having the issue in 2018.1 RC1.
Case number is 1000696.
This is the QA message about reproduction:

I tried all possible solutions I read, but still happens.

@okcompute_unity Yes I'm sure 1000696, I quoted the response

 

Hello @xCyborg ,

I would love to see if I can reproduce your setup in order to, ultimately, get this bad issue addressed for all the users running into it.

I apologize in advance for potentially making you repeat any information previously posted on other threads, but could you possibly provide me an idea of what your setup/configs are:

• OS
• network settings
• proxy
• firewalls
• environment variables
• antivirus

I've tried the exact steps shown here: https://issuetracker.unity3d.com/is...s-modules-when-an-internet-connection-is-slow

I've also attempted other network tools (clumsy, Fiddler), as well as a closed network physical setup we have running here (basically various settings of a router not connected to the internet0 to no avail in any case.

Thank you in advance for your help with this defect.

Cheers,
P

 

@pedro_unity That's identical to my issue.

Here is my setup:
-Windows 10 1709 64bit
-private network, metered connection / wifi
-no proxy or network related environment variables
-unity editor allowed in inbound rules
-antivirus is windows defender, I followed an advice and added an exclusion to upm-win.exe but didn't solve the issue.

I hope this helps, also if you could contact the guy who reproduced it.

 

Thanks @xCyborg,

Thanks for being willing to help us sort this out:

• If you're comfortable with starting Unity from command line, please do so by adding the argument "-enablePackageManagerTraces" (without the quotes after Unity.exe). So in my case, from the command line, this would look like this:

• Please attempt to add a package once again or start Unity to provoke the error message. Let me know if that fails. If it fails, please send us the logs. The argument adds more information about the CURL requests done by upm.

After this:

• Would you please confirm you have write rights to the folder mentioned here C:\Users\tg\AppData\Local\Unity\cache\packages\packages.unity.com
• Additionally, if you do have permissions to that folder, could you kindly delete the cache contained here: C:\Users\tg\AppData\Local\Unity\cache\packages\packages.unity.com

Once this is done:

• Would you please attempt to add a package once again or start Unity to provoke the error message once more. Let me know if it works.

Thank you so much @xCyborg,

Cheers,
P

 

@pedro_unity I did as told.
Started Unity with command option above, the logs are too large, so...
Here is the log file after failing to add a package from package manager:
https://1drv.ms/u/s!Ato44WJy5busqHyJ-Tm1vv7cLYU6
And after deleting the cache and restarting Unity and also failing:
https://1drv.ms/u/s!Ato44WJy5busqH1IFOyq_aTtB8Sb

 

Thanks @xCyborg ,

I took a look at the logs, along with a couple of our engineers. The POST operation when you attempt to add is failing (you probably saw this yourself):

We have some reports that point that this is caused by a proxy blocking the POST operation, especially since your GETs are functioning without a hitch.

Unity Connect/other parts of Unity are also sporadically failing which also points towards this.

Are you positive you're not running a proxy that could be blocking/shaping traffic towards upm?

Let me know - we will continue investigating,
P.

 

@pedro_unity I double checked, there is no system proxy defined in Internet Options or Settings > Network & Internet > Proxy.
I want to mention that traffic is not completely blocked from upm, it downloads fine before the timeout, and even after the timeout it continues to download the package in the background (checked Task Manager).

 

Thanks @xCyborg

Just to make sure, this happens on every version of Unity you tried (since 2018.1), on existing as well as new projects?

I'll keep digging on my end. Thanks for the help!
P

 

@pedro_unity Yes, I tried almost all betas, existing and new projects alike, same behavior.

 

You are, to the best of my knowledge, the only user to whom this problem persists despite cache clearing and is not subject to a proxy, firewall or rights issues.

We are having a talk internally in a few hours to discuss how we get more diagnostics/next steps in to be able to find exactly what your problem might be.

Thank you very VERY much for your patience, @xCyborg, stay tuned!
P

 

We haven't forgotten you. We're working on some diagnostics and will make sure to loop you in as quickly as possible.

Cheers,
P

 

Hello @xCyborg,

If you have the time, we're going to try a POST directly through the means of a html file (attached below) and Unity Package Manager running (but not Unity).

By command line:

• Locate your Unity executable path.
• Navigate to 'data/resources/packagemanager/server' and start the Windows executable named 'UnityPackageManager'.
• Unzip the attached html file named 'test.html.zip'
• Double click it and a browser window should appear. Click the submit button in the web view. Please ignore the wrappings

the response should NOT be :

Code (JavaScript):

1. This site can’t be reached
2. localhost unexpectedly closed the connection.
3. Try:
4.  
5. Checking the connection
6. Checking the proxy and the firewall
7. Running Network Diagnostics
8. ERR_CONNECTION_CLOSED

The response should be:

Code (JavaScript):

1. {"message":"Invalid content type (application/x-www-form-urlencoded).  These are valid: application/json"}

Thanks for your patience, let me know.

Cheers,
P

 

@pedro_unity There is no UnityPackageManager executable in the specified directory, so I ran upm-win instead from the command line.
After clicking submit in the test web view, the response is indeed:

Code (JavaScript):

1. {"message":"Invalid content type (application/x-www-form-urlencoded).  These are valid: application/json"}

 

Hello @xCyborg,

I sincerely appreciate your patience in helping us deal with this pesky issue.

With the previous simple test we proved that you're capable of connecting to upm-win.exe localhost port 10010. I would like to eliminate two other factors if you have the time.

• You can also connect to 127.0.0.1 (which is the IP we use for local upm transactions)
• You can use higher ports (Packman tends to use ports above 50 000).

To do so I would kindly ask you to restart upm-win.exe (Unity Package Manager server) through command line using the command:

• upm-win.exe -p 53200

And unzip, click and use the submit button on the attached file test2.html.zip which will connect to 127.0.0.1 port 53200 and attempt to do a POST operation.

• Please click on the submit on the web page that will open after double-clicking on the unzipped test2.html file.

Once more, thank you very much for your help.
Cheers,
P

 

@pedro_unity Once again, it connects just fine to

http://127.0.0.1:53200/packman/packages

Code (JavaScript):

1. {"message":"Invalid content type (application/x-www-form-urlencoded).  These are valid: application/json"}

I'm thinking more it's due to some unfortunate timeout rather than connection issues.

 

Hi @xCyborg,

It is unlikely but perhaps a timeout is at fault. We have disabled timeouts for this type of connection. The issue you're running into is not common place, therefore we have to approach it sequentially and attempt to remove variables one by one.

You have been an incredibly good sport in helping us out and at the risk of having your patience grow thinner I would ask you two additional things:

• Can you, in the package manager UI, remove (delete) a package? Does this operation work?
• Would you send us the UPM logs (they're located here:
  C:\Users\username\AppData\Local\Unity\Editor\upm.log - next to the Editor logs)
• More info: https://docs.unity3d.com/Manual/LogFiles.html

Thank you very much!
P

 

Hi @pedro_unity,
And thank you for following up on this.

• Removing a package from the package manager UI works as expected, no events raised.
• UPM logs are mostly empty, even after provoking the error by installing the new Post Process package.

I enabled full stacktracing on errors, maybe we missed something:

Cheers,

 

Sorry for the delay @xCyborg,

Looking at the logs now. Will get back to you as soon as possible.

Cheers,
P

 

I forgot to mention: We have an updated version of Unity, probably out next week, 2018.1.0f2, that contains some fixes that will potentially address this issue. The build contains an updated upm executable.

Meanwhile, would you be open for us to contact you directly and remote desktop to your machine?

This might be the best way to obtain information on your particular condition.

Cheers,
P

 

Hi @pedro_unity I installed Unity version 2018.1.4f1 on all the machines on my network but the same problem persists always.
If you want you can hit me on TeamViewer for remote control.

 

Alright, let me set it up with the team and get a date / hour that works for you. I'll send you a private DM with yet more questions.

Cheers,
P

 

Hi @xCyborg,

​

I've just talked with the team and we think that we haven't exhausted all options and debugging might not give us the results we want to because the error is a HTTP code 0.

• Have you tried 2018.2 release at all or only 2018.1?
• You said at one point that all machines on your network have been updated. Are they all Windows machines? Does Unity exhibit the same behaviour on all?
• Can you tell me what the response is when you visit this website:
  • http://amibehindaproxy.com/

Thanks,
P

 

• I already tried 2018.2 beta, it's the same behaviour.
• Yes, they're all Windows machines, they exhibit the same behaviour.
• I already tried that site, it says "No proxyserver detected."

 

Thanks,

Would you be able to completely deactivate:

• Windows Defender
• Windows Firewall

We suspect that one of these is the potential culprit.
Cheers,
P

 

Disabled them both, same old error.

 

We have an internal event next week, so expect belayed responses. Apologies in advance.
More questions:

• Do you have anything on the hosts file that could affect connectivity? Can you possibly share that with us?
• Do you have access to another network, a guest or a network cafe?

I'm still trying to eliminate all network possibilities. Thank you so much for your help!

Cheers,
P

 

I just wanted to say thank you to @pedro_unity for his determination to find the culprit of this issue and to @xCyborg for providing all the information. You guys rock!

 

Thank you @Peter77 for the encouragement! It pains us when there are obscure issues like these that stop folk like xCyborg from operating the software.

Cheers,
P

 

Hi, sorry for the delay, I tried different networks but same behaviour always.

Just a new error I guess:

Cannot perform upm operation: Unable to add package [com.unity.cinemachine@2.2.0]:

  Access to manifest [C:\Users\HP\Documents\Unity Projects\3CPO\Packages\manifest.json] is denied [Unknown]

 

Hello @xCyborg,

Interesting, this seems to point to a rights issue. I was sure we had previously confirmed that you had write rights to the project folder. That [Unknown] error is troubling. I'm going to do some research with the team to understand under which circumstances that is passed from npm to Unity.

Cheers,
P

 

Hello @xCyborg, everyone,

We think we have finally identified the issue you're suffering from. When you add a package in the Package Manager UI, it first queries the local UPM server who acts as a bridge to the distant Unity registry in case the package is not found locally. There was a 2 minute timeout between the Editor and local UPM server that was blocking the "add" operation you were attempting.

I'll let you know when/how this will be fixed and I'll inquire to see if we can send you an improved version of UPM to unblock you.

Cheers,
P
