Why can't I run update-manager-d to upgrade?

Question

I'm semi-new and not an idiot with computers. I can't get update-manager-d to run and it says that their is no such thing. Can anyone help me?

Answer 1

You're looking for update-manager -d (note the space). update-manager is the name of the program, d is an option flag.

You indicate options with a dash (update-manager -d) when they are a single letter (which most are), and you indicate them with a double dash (update-manager --devel-release) when they are a word. Often, both forms are available for common options for a program. Run man <program-name> for more details on the program's available options.
