I think I screwed up something with piaware but I don't know


#1

Good afternoon.
Please don’t rake the newbie over the coals.
This may be pointless to point out but I am new to raspberry pi and piaware.
I installed v. 1.13 by following the directions and it worked perfectly and has been for almost two weeks. I noticed on the Anomalies tab that I am behind and should upgrade to v 1.15. The instructions were so simple. How could I screw it up?
Well, …
The upgrade process isn’t working but I noticed as I was doing it that suddenly there was “cd” at the prompt. I couldn’t seem to get rid of it and my research online just said it listed a directory so it seemed harmless enough to hit return to make it go away. I think I may have erred…Now, my prompt is no longer "~" but is now " "/ home"
This can’t be good and restarting pawer hasn’t made a difference.

How do I get back to the original prompt?

…and would this explain why when I follow the directions to download the update that I am told "Cannot write to pawer_1-15.-1.deb (Permission denied)

Thanks for any advice.

The cd command changes the working directory; the working directory in turn is displayed in the command prompt. Notice how the prompt changed from ~ to /home; this is the indication that you changed the working directory. The “permission denied” message is because your user doesn’t have the necessary permissions to write a file to the /home directory.

Fortunately, there’s an easy way out of this. Simple type “cd” by itself at the prompt and you’ll be returned to your home directory, where you should be able to perform the update normally. Example:


pi@piaware /home $ cd
pi@piaware ~ $ wget http://flightaware.com/adsb/piaware/files/piaware_1.15-1_armhf.deb

Pclifton,
That couldn’t have been any easier, huh? Thank you. Thank you very much.
I corrected the directory and updated to 1.15 in less than three minutes.
Thank you for taking the time to help the hopeless. Let’s hope this is the last goofy question I need to ask.
