Re: Raspbian Jessie zip appears corrupt

Really, folks. Just use NOOBS Lite. You'll be glad you did. And remember, NOOBS *is* the approved/recommended way. This "raw image" stuff is really only for hardcores. Perhaps, but Raspbian is the official distro of the foundation. I think that breaching learning curve of dd'ing the image under nor...

Re: Raspbian Jessie zip appears corrupt

My solution was to unzip the jessie .img to an ext3 filesystem Did this cure your dpkg status problem? From what I recall the error I got from unzip was the same as that from xarchiver (can be viewed in realtime with action>archive>store archiver output checked; sorry don't have it to hand) was rel...

Re: Raspbian Jessie zip appears corrupt

You still have problems with 7zip unzipping to a FAT32 disk (max file size 4GB). Ended up using Linux. I tried without success to unzip it to a couple of vfat drives; xarchiver gave me: "write error (disk full?)" .img is probably truncated 7-zip returned: ERROR: E_FAIL I dd'd it anyway (ignoring th...

Re: Unable to parse package file...

I was getting the same error trying to update a fresh install of jessie; I had ignored the error from unzip when uncompressing the image onto a vfat filesystem. The problem was that vfat is only capable of 4gb files or less and had truncated the 4.3 gb raspbian image to 4gb. Hence I encountered the ...

Re: Powered hub requirements

The USB2-HUB-AG7 has a special Mini-B port labeled "USB IN" that is used to connect to one of the vertically stacked Type A ports of the pi, and this connection will not back feed voltage into the pi. The pi is then powered properly by connecting one of the 7 Type A ports of the hub to the Micro-B ...

Re: Powered hub requirements

That explains it, rpdom. All good aside from
spilling coffee on it, connecting it wrong, a power surge, a lightning strike, a short in a cable between a device and the raspberry pi, etc

Re: Powered hub requirements

Ha, ha,

sounds like the polyfuse is at the wrong end of the circuit-board!

Saw the post featured on the front page of the site yesterday. As I had just received my hub the day before I decided to sign up to the forum and undertake that daunting first thread

Re: Powered hub requirements

That sounds nasty :(. A raspberry pi then is at risk from a back-feeding power-loop; some hubs' 'power supply units' have been designed without protective built-in fuses and diodes (unlike the USB2-HUB-AG7), and therefore are unsuitable to users powering the main device (like the raspberrypi) via th...

Re: Powered hub requirements

I see. No back-feed means the pi gets it's supply as per normal with no other current slipping back to the pi from the usb devices connected to the pi. However back-feeding must be fairly common on many pi's connected to hubs without back-voltage protection on 'upstream connections' . What's the wor...
