Re: sudo apt full-upgrade = green light of death

Just adding an observation. I realised tonight that whilst I've had no issues with these Toshiba Exceria cards before, I haven't used them on a Pi4 previously. I also realised that my other functioning Pi4s (3 of them) without issues (that I haven't attempted the upgrade with as I'd like to keep dea...

Re: sudo apt full-upgrade = green light of death

Something's definitely not right. I just checked my mining pool and this same Pi was offline. I tried to SSH in - nothing. So I cycled power and now the green light is on again. Note that this was without trying the upgrade. I tested the SD card as instructed, no issues detected. I wonder, is there ...

Re: sudo apt full-upgrade = green light of death

So what size SD cards are you trying to use , I would recommend no smaller that 8GB for raspbian lite, I would also recommended testing your SD cards with H2testW to see if they are failing or fake, I would also recommend downloading a fresh copy of raspbian just in case there is a problem with the...

Make, model and size of SD cards? What are you using for a power supply? Have you verified the SHA256 hash sum of your Raspbian download? Have you tested your SD cards with h2testw or a similar flash memory verification utility? Describe your procedures for setting up your system (the answer might ...

I've just noticed your location. There are active Pi users in your area, some of whom may be able to help you test things. I don't know if you are aware of SOSLUG? (Southend-On-Sea Linux User Group). They have run a few Raspberry Pi events here in Chelmsford. Yes I went down to a few SOSLUG meeting...

Re: sudo apt full-upgrade = green light of death

Just happened again with a different SD card.

Fresh Raspbian Lite install, same process, same green light after I followed the upgrade process.

So, I've just written a fresh image AGAIN and this time I get the green light before doing anything at all.

Now I'm really confused.

Re: sudo apt full-upgrade = green light of death

Mine are all 2GB models. All running Raspbian Lite.

Just tried another SD card - works fine. Same Raspbian image file I used before too. I'll now try the same upgrade with this one and see what happens.

You can leave these out if connecting to an amplifier but it's your choice.
That's exactly what I'm doing, this feeds straight into an amplifier.
