This was solved after rebooting my computer. Do you still think it's worth keeping it opened and investigating?
That means your command-line package manager was open and/or in use. We figure that if you're an expert enough to use a command-line package manager, you can interpret the error message to figure that out. :0 It's a bit cryptic for sure, but it comes from the process itself rather than Discover, so we can't really improve it, sorry.
