Failed to connect to wpa_supplicant - wpa_ctrl_open: No such file or directory

to whom it may concern:

Expected target:Any penuin who hit the message
Failed to connect to wpa_supplicant - wpa_ctrl_open: No such file or directory
and after dogpiling your dog came back with this, this or something else.

Solution: Unfortunately, (at least for me), this is NOT a bug. Nobody's fault, but me. It is crystal clear.


What happened: I way trying to check several interfaces, I replaced interface with some other one, udev was so kind that wlan0 and wlan1 both exist. Then I tried to
ifup wlan0
where actual interface for wlan0 does not exist. That's how I got the error. I was sure that because only one interface exists, it was wlan0. I should have invoked wlan1, not wlan0.

Take home message:Don't be silly as I am.

Closing remarks:Happy Penguins!

System:Debian testing, but I don't think it matters.
