Although I am sure you have moved on, the answer provided in the FAQ isn't quite right to answer your question.

https://forum.elecrow.com/discussion/69/what-are-the-internal-dimensions-of-the-storage-tray-for-power-bank#latest
"The internal dimensions of the storage tray are
147 x 78 x 9.5 mm
5.79 x 3.07 x 0.37 inches"

The tray on my unit includes 6 plastic supports / spacers inside the tray as well as a proud rubber button on the front. As a result, without physical modification, the tray will not accept power banks up to the listed dimensions.
My tray will only accept power banks up to.
146.5 x 69.5 x 9.5 mm

New to CrowPi2.
I need to apply updates. Whenever I do I get an error which is truncated so I can't read it in full.
Is there a log file so I can see what the error is?
Is there a copy command for a dialog window so I can paste it elsewhere.
Any advice on how to complete the updates would be appreciated. I have tried quite a few times and each has failed. I was hoping repeating the updates would eventually work just leaving the failing one in the queue. No such luck.
I have an image of the problem but it has to be hosted somewhere as you have to specify a URL. Can someone please let me know of a suitable service/server I can use? Its A long time since I had to do anything like this.

PeterM

You can upload an image. Thats great!!
