All versions - Error message "Package failed" when trying to download and install packages

WARNING: Before trying the troubleshooting steps below, switch to an LTE or wired connection. This will help ensure that you are on a stable internet connection. A wired connection greatly reduces the risk of packet loss responsible for that error message.

If you're using an LTE or wired connection, manually delete the official package and any corresponding Community Created Content that may prevent the installation.
