Description
I am trying to execute ng update @angular/core@20 @angular/cli@20 to perform angular upgrade from version 19 to 20. However the cmd execution stops after emitting the warning "Installing a temporary Angular CLI versioned 20.0.1 to perform the update." without emitting any useful errors.
I am using yarn 4.4.1 as my package manager. In package.json, I have set "packageManager": "yarn@4.4.1" and "packageManager": "yarn" in angular.json cli property.
Minimal Reproduction
$ ng update @angular/core@20 @angular/cli@20
Exception or Error

The installed Angular CLI version is outdated.
