Error opening terminal: xterm-256color.

[laputa:)]

I've recently been running kismet on my Mark V and all was going well until I booted up the pineapple a couple of days ago and I couldn't access the sd card or modify a file in the terminal using nano. I've bought a new sd card and all seems to be working fine there but I still can't solve the nano issue, I keep getting the following error :-

Error opening terminal: xterm-256color.

I've done a factory reset and re-loaded the firmware (2.4.0) and neither have fixed the error. Does any one know how I can resolve this error?

Thanks.
