Package Manager window

Use the Unity Package Manager (in Unity’s top menu: Window > Package Manager) to view which packages and feature sets are available for installation or already installed in your project. In addition, you can use this window to see which versions are available, and install, remove, disable, or update packages and feature sets for each project.

The Package Manager window displays:

(A) The experimental package indicator, which warns you if your project contains experimental packages.

(B) The add button, which you can click to install a package directly into your project by entering a git URL, a local path, or a package name.

(C) The Packages drop-down menu, which you can use to change what appears in the list (context).

(D) The Sort drop-down menu, which lets you sort the list of packages and feature sets by name or date.

- Add, edit and remove scoped registries in your project.
- Show pre-release packages when browsing the Unity Registry.
- See which packages are installed as dependencies of another installed package (indirect dependenciesAn indirect, or transitive dependency occurs when your project requests a package which itself “depends on” another package. For example, if your project depends on the alembic@1.0.7 package which in turn depends on the timeline@1.0.0 package, then your project has an direct dependency on Alembic and an indirect dependency on Timeline.

Status bar

The Package Manager displays messages in the status bar at the bottom left of the Package Manager window.

There are typically four status messages that you might see:

The first time you open the Package Manager window in a new project, the Refreshing packages message appears briefly:

Loading packages message

This message also appears when you select Refresh list from the reload drop-down menu.
When you are using the My Assets context, the load bar appears above the date. It displays the number of Asset Store packages and a Load link:

On the left, the load bar displays the number of Asset Store packages loaded vs. the total number available. Click the Load link on the right to load more (in this case ‘All’).
Most of the time the status bar displays the date and time of when the Package Manager window last refreshed its information. However, if the Package Manager detects a problem, such as a missing network connection, the Package Manager displays an error in the status bar:

Network error message
If your network connection is working, but you are not signed into your Unity account, the Package Manager doesn’t display any Asset Store packages. When you try to use the My Assets context, the Package Manager displays an error in the status bar:
