Hello, Thanks for posting this very helpful guide. I’m stuck though. I think I checked all of the right boxes and performed the correct settings at setup, but after installation and reboot. I get a line of code asking for “c” to continues, “l” for library and “q” to quit, but none of those letters work alone. What else do I need to type there? Thanks in advance, Dave
I didn’t understand the message, can you please share the screenshot to [email protected] so that I can have a look.
