An Ubuntu user could use OS-Uninstaller to accomplish this task safely without deleting his data. OS-Uninstaller is a component of Boot-Repair. My question for you is do you think it's OK to use system-uninstaller for a tag name and system-delete for a tag synonym?

@Braiam Maybe I should call it system-delete.

@Flimm I'm already familiar with that excellent linked question, and I upvoted both the question and its accepted answer.

Does this answer your question? A note on flagging end of life questions
