Question Error: Failed to add editor bundled package. ENOENT: no such file or directory. mkdir

Hey guys, I've just installed Unity for the first time and when I create a project with the 3D Mobile Core template I get this error every time 'Failed to resolve packages: Failed to add editor bundle package. (Photos attached for reference). I've reinstalled it several times and tried changing the install and download locations but keep getting the same errors. I want to learn Unity but I haven't even got a chance to start yet. Please help.
Thank you.
This is the first error

And when I click Retry I get this:

And when I click continue I get the 1st error again.

 

I have the same issue, did you fix it?

 

This was driving me insane. I just fixed mine. This may help.

The ENOENT (error no entity) error refers to Unity not being able to locate your packages cache folder. We can set (or unset) Windows environment variables to point Unity in the correct folder path.

The default cache folder location for each operating system is as follows:

Windows (user account) - %LOCALAPPDATA%\Unity\cache
Windows (system user account) - %ALLUSERSPROFILE%\Unity\cache
macOS - $HOME/Library/Unity/cache
Linux - $HOME/.config/unity3d/cache

Now we'll create (or edit) an environment variable for the Unity Cache folder. You can use the default folder location or make a new folder on an external drive to save space on your internal drive.

Right Click "This PC" and Select "Properties"


Select "Advanced System Settings"


Press "Environment Variables" Button


Press "New" Button In "System Variables" Section (Or Edit If You Have An Old Variable Set)


Type "UPM_CACHE_ROOT" In Variable Name Field and Press "Browse Directory" Button


Navigate to either the default folder location above or to your new folder.

After exiting those windows, fully exit and restart Unity Hub for good measure.

Before creating a new project in Unity Hub make sure all your packages are actually in the folder you're pointing to.

You can now open older projects or create new ones (so long as the editor versions you're choosing are installed properly). To check if Unity is searching for your packages in the correct folder open a project (new or old) and inside the Unity editor select Edit Menu > Preferences > Package Manager > and then check Cache folder locations for your packages and your assets.

 

I just noticed your Windows username has an apostrophe in it. There is a recently discovered issue with special characters in folder paths. To fix, either make a new profile on your computer or change your account name to not have any special characters in it.

If I look carefully at your two pictures I can confirm the folder paths are different. One shows "DArt" and the other shows "D'Art".

 

Another reason this can happen is if you have an apostrophe in your project title name, which is what happened to me.
