I have been used to waiting for the 10 blinks on shutdown of jessie-lite. I'm on "full" stretch now, and seeing the green LED flash 30 times on shutdown. Is this the new normal, or has my Pi gained consciousness and is trying to tell me not to shut it off?

Do you plan on using two wifi devices? If so, you should use persistent network names. Otherwise, it is almost impossible to tell which names they will use. How is the signal after you reboot? Use iwconfig to check. Plan: No I don't want to need the dongle, but the on-board is no long working well ...

Issue: Intermittent WiFi over built-in Pi3 interface, "Release file not found" on apt-get update Work-around: Use USB WiFi dongle (or wired Ethernet) for wlan0 (try reboot again if dongle configures as wlan1) Aspects: ifconfig shows no packet errors or dropped packets. Issue seen on Jessie...

I didn't see a BOINC project thread - sorry if this is a dup. I have a desktop Pi3 which has nothing to do for most of the day, so I installed BOINC and joined the RaspberryPi team running Einstein@home tasks. I also configured 25% of my BOINC processing to go to the SETI@Home project. Originally, m...

I have had two Samsung EVO 16g cards “die” with this same MO over the last year.

Try to update setuptools

Thank you, that seems to have done the trick.

$ sudo pip install --upgrade setuptools

See those ipv6 addresses?

Try disabling ipv6:

$ sudo nano /boot/cmdline.txt
And add at end of file this:
ipv6.disable=1
(Ctrl-x, y, return)

$ sudo reboot now

Now try your update again.

It appears this particular Pi3 may have developed a built-in WIFI problem. It was working fine for the prior six months. Then I had the SD card go "read-only", and now this. I tried curl http://mirrors.ocf.berkeley.edu/raspbian/raspbian/dists/stretch/Release. On my mac it succeeds. On my D...

Someone, please tell me what is wrong in my world? This is the Stretch experience: 1) downloaded 2017-09-07-raspian-stretch.zip 2) put it on 16gb card with Etcher (using Mac) 3) Pull out, reinsert card to mount boot partition 4) add wpa_supplicant.conf to boot partition: country=US ctrl_interface=D...

I don't think this is a DNS issue. When I browse the archive, the armhf package really does not exist - only binary-armhf exists, in both main/ and ui/ Err http://archive.raspberrypi.org jessie/main armhf Packages 404 Not Found [IP: 93.93.135.188 80] Err http://archive.raspberrypi.org jessie/ui armh...

Okay, that got me curious, so I made two freshly imaged SD cards with the last Jessie and the current Stretch and tested them both in my Pi Zero with a Raspbian compatible USB WiFi dongle. This leaves me wondering if you are having DNS issues with your ISP? Try changing your DNS to OpenDNS or Googl...

Going back to Jessie is actually a fine option, Actually, something too weird - 2017-07-05-raspbian-jessie complains about the same files missing, and tries IPv6. The IPv4 issue I can fix, but the missing files on a clean install, makes me question the repositories: $ sudo apt-get -o Acquire::Force...

My "jessie-lite" robot recently had its SD card turn read only, so I decided to try rebuilding it on Stretch. The initial hurdles make me wonder if my 17 year old robot should wait until Stretch gets over "growing pains". The first two steps in my build process are: 1) update the...

Also tried:

Code: Select all

$sudo mv /usr/share/python-wheels/urllib3-1.19.1-py2.py3-none-any.whl /usr/share/python-wheels/urllib3-1.19.1-py2.py3-none-any.whl.bak

StackExchange post suggested "remove /usr/share/python-wheels/urllib3-1.19.1-py2.py3-none-any.whl" worked for that person.

Edit: A quick Google search shows maybe you should use an app named TextEdit instead of textapp. TextEdit is the editor I used. I discovered my problem: I had copied the text from a web page and pasted it into TextEdit. The quote chars from the web were the Unicode left/right double quote!! My old,...

I use Python on my robot. There are great open source examples of Python available for the GoPiGo robot. BTW, GoPiGO is a well designed robot, with excellent forum for their users, and educators. If I was starting out to build a robot again, I believe the GoPiGo is the best platform and support syst...

Is there a power cell or a power pack I should look for in particular for this issue? To give good suggestions, we need to know a little more about your robot, such as: 1) Which Raspberry Pi board are you powering? 2) Are all the motors/servos powered separately from the Pi board? 3) How much run t...

Did you not read my posts? I just did two headless installs that went fine. "Works for me" really doesn't feel good to those of us that are seeing this issue. You may be onto something about what editor is used to create the wpa_supplicant.conf file. My recent headless stretch flogging se...

Anyone know if there is a work around mirror? You could (temporarily) change the URL in /etc/apt/sources.list to one of the mirrors: https://www.raspbian.org/RaspbianMirrors http://mirrordirector.raspbian.org/raspbian/ is not working for me at the moment, so tried: deb http://raspbian.mirrors.wvsta...

I just finished two days of flogging with "wlan0 not associated" with 2017-09-07-raspbian-stretch on a Pi3 that was playing nice under jessie-lite. I tried the headless method with: wpa_supplicant.conf per the thread head: country=US ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev ...

solid aluminum case Indeed, that worked very nicely till I wanted to add a LIFePO4 UPS to protect my SD card from power failures. Pi3 is mounted vertically (on edge) in free air. A 15mm cube heat sink is stuck on with 3M thermal tape. That is how I was running with the UPS until I came home and fou...

I am wondering if optimal processing on my Pi3 might result from allowing short bursts of temperature caused throttling. I have been running Einstein@Home/BOINC on my Pi3 with load limits tuned to prevent temperature throttling. At these settings, the temperature hovers around 71 degrees C, and will...
