Hi @lchunleo,

I am not an expert on this but I think this error is probably introduced by the lack of internet connection on another computer? I find some discussion here: proxy or firewall preventing packman to download packages from the registry. especially they said,

This issue is usually caused by a proxy or firewall preventing packman to download packages from the registry. Please make sure your network configuration is good like here: https://forum.unity.com/threads/network-configuration.590470/

Please let me know if that helps.

Thanks ruiyu,

i find it strange given that the packages has already been downloaded from the internet previously when i worked on it. i only just copied the entire folder out and placed in another computer. i just wondering why the perception would try to get the package from the internet?

Hey @lchunleo, can you send us your Editor and UPM log files? that might be helpful to identify the issue

@JonathanHUnity do you might know what is happening here?

Hi @lchunleo This is a problem with the package manager trying to access the internet for one or more packages. While I'm not sure why this is happening, you can probably remove those packages from your Packages/manifest.json file as a workaround. If you look at the upm.log file you would be able to find which packages are causing the issue. Here is a guide on where to find this and other log files: https://docs.unity3d.com/2020.1/Documentation/Manual/LogFiles.html
