Import button not showing in package manager

Silent_al · October 24, 2024, 10:51pm

Import button is not visible in the package manager; this issue appeared after I installed Unity 6.

The asset hasn’t been downloaded yet. You can see the download button there.

Silent_al · October 24, 2024, 11:17pm

When I try to download, it only shows the download button and nothing else.

Hello! Is this still an issue? If so, could you provide more information please:

Are all your assets showing up in the My Asset section?
Do you see anything in the console?
When you click on the Download button, nothing happens at all or do you see the download process?
What is the full Unity editor version you are using?

Silent_al · October 30, 2024, 12:45am

Hi Solution Penguin,

Yes, this issue is still present.

In response to your first question, all my assets are showing up correctly.

Regarding your second question, I encounter two errors when I click the download button. The first error is

FormatException: String was not recognized as a valid DateTime.

and the second error is

For your third question, when I click the download button, a download progress bar appears. However, once the progress finishes, nothing happens.

As for your fourth question, I am using the current version of Unity, which is Unity 6.

SolutionPenguin · October 30, 2024, 6:15pm

I can’t reproduce your issue, I was wondering, what exactly did you do to have this error? Was the project on another unity editor version before?

Silent_al · October 31, 2024, 2:07am

No, this is a new project.

pax_unity3d · October 31, 2024, 7:49pm

Hello Silent_al, one thing I notice in your screenshot is that the asset is not loaded properly, did it ever load completely? Showing the description and such? We are not able to reproduce your issue, could you provide a screen record of your process and maybe the editor and package manager logs:
On mac:
Editor: ~/Library/Logs/Unity/Editor.log
Package manager: ~/Library/Logs/Unity/upm.log
On windows:
Editor: %LOCALAPPDATA%\Unity\Editor\Editor.log
Package Manager:
User account: %LOCALAPPDATA%\Unity\Editor\upm.log
SYSTEM account: %ALLUSERSPROFILE%\Unity\Editor\upm.log

Hello again Silent_al,

Thank you so much for your collaboration, we were able to identify what is the issue and we created this ticket to fix it on our side: Unity Issue Tracker - User not able to download an Asset Store package if the data is corrupted with the publish dates. Feel free to keep track of it to see when the issue will be fixed. This is a rare problem where one of the assets in your cache might have corrupted data and is affecting the complete loading of your assets.

I can suggest that you delete your My Assets cache and see if it fixes your issue for now. You can see where your cache is in the “Preferences” window under the “Package Manager” section. You can see how to access it more clearly here: Unity - Manual: Customize the Asset Store cache location

PLEASE NOTE: I would highly suggest that you back up your cache folder somewhere just to be safe before deleting it.

Please let us know if this works for you if you decide to try it. Sorry again for the inconvenience, we will make sure to fix this ASAP.

Silent_al · November 8, 2024, 6:42am

Hello pax_unity3d,

Unfortunately, the issue persists after following your suggested steps. I’ve tried deleting the cache, but the problem remains.

Please let me know if there are any other solutions or workarounds I can try.

Thank you for your time and attention to this matter.

Silent_al · December 7, 2024, 2:34pm

If you’re experiencing issues similar to mine in Unity 6, I recommend downloading Unity 6000.0.30f1 or a newer version. This resolved my problem and may help you as well!.
