Unity3D Package Cache errors(?)

Question

After deleting and installing Unity due to a problem it caused me, these errors appeared in the console. I've already tried to reinstall Unity but they won't go away.

EDIT: I get these errors in every project I open.

Answer 1

Open your project in Unity first.

Then follow these steps.

• Go to C:/Users/Your User Name(Utente for this question)/AppData/Local/Unity/cache/packages/packages.unity.com (The path that is shown in error)
• Delete all of those folders you see in that packages.unity.com folder.
• Go back to Unity & let it recompile it. Your errors must be gone now.

Answer 2

for me clicking reset packages to defaults in advanced of the package manager window
