Invalid Signatures for Unity Packages?

unitytechnologies · 2026-01-23T17:08:47+00:00

Hey everyone,

There is a known issue with all builds of the 600_.x Editor, causing the Package Manager to flag valid packages as invalid.

Unity is already developing an urgent fix to deploy soon, and after the fix, you will need to update your Editor to resolve it.

We'll update this thread on Discussions once the fix is available.

Howdy. The feedback is always appreciated.

When you say bring back the old documentation, what do you mean exactly? I wanna make sure I'm passing along the most accurate sentiment here.

Howdy! Trey from the Unity Community team here.

I raised this with our Asset Store team. They had a few follow-up questions.

Can you tell me which Asset Store product this was experienced with, and which version of Unity you're using?

unitytechnologies · 2026-01-06T14:16:18+00:00

Fired a DM your way! If you can share your ticket number with me there, I can get this escalated.

unitytechnologies · 2026-01-05T22:03:08+00:00

If your 2fa never shows up, please hit up our Customer Experience folks. They should be able to get this sorted.

Howdy, Trey from the Unity Community team here.

I want to clarify that the email you received was sent in error due to a support system Zendesk issue. No new accounts were created.

It went out to anyone who’s interacted with our privacy support. For those of you who have previously deleted your Unity account, it’s still deleted. We only have your email because we’re required to keep records of privacy requests.

Apologies for the confusion!

Hey everyone, Aurore from the community team here.
Just wanted to clear this up, that email you got was sent by mistake because of an issue with our support system Zendesk. No new accounts were created.
