RPI3 speedtest-cli and 'sudo apt-get update' problems

But if due to the SD problems (read only) sudo apt-get update can't write the updates in the SD, the error 404 automatically remains ..... don't you think it can work like this ?

You can get 404 errors when doing an apt command with a very poor WiFi connection.

I've now got so many Pi's they need to be treated like a herd rather then pets, so I have scripts to simultaneously run commands on all of them. When using this to do a update there is so much WiFi traffic the Raspberry Pi in the shed at the bottom of the garden throws 404s. If I go back and kick it off manually, it succeeds, albeit slowly.

It only has a standard RPi WiFi dongle, I'll probably upgrade it to one with a large antenna, like the one I use for video streaming in the Family room. Although that is inside the house, its was in a complete dead zone as far as a standard dongle was concerned, but the one with the antenna has a better signal than the RPi3B's built in WiFi 15ft from the router.

this is not specific to the RPi at all... you'd get the same on any other OS in the same situation...

No. 404 means the server couldnt find what your pi asked it for, or whatever is masquerading as the server. It didnt mean the pi got it and failed to write it.

You can look in /var/log to see what if any other errors there are.

As I said last post the pi dioesnt store the update file list in itself either, it stores only what repostiories to check. Once it gets to the repository it downloads a list of all the files to itself and tries to download them one by one. For some reason its downloading a list of files some of which are not on the server. My guess is a stale cache in a transparent proxy.

i,e, there is a hierarchy

go to server download master list of listts download each list...but some lists in the master list of lists are apparently not on the server.

Except to other pis, they are?

What is unique to this pi?

Its internet connection is via a mobile signal.

Hpw could that make a difference?

Mobile ISPs masquerade IPs and use just a few ip addresses but that should NOT be an issue

Moble IP may cache web pages to avoid using huge amounts of internet bandwidth. Its shoddy but some do.

If the cache isnt well configured it might cache old data.

*shrug* my best guess.

it is cacheable if there's a MitM setup in place... i'm aware of many such setups specifically to protect the network from infestations if a nasty is attempted to be downloaded...

Let me jump into the thread here, and let me be blunt ...

we *know* it can't work like that.

The 404 error is 100% certainly the server saying "I haven't got the file you asked for". It's possible you do have a faulty SD card, but it's impossible for your SD card (faulty or not) to cause a 404 error.

Thank you @Andy Burns for saying your opinion .... but from how you write it seems to be technically verified ... Initially I also thought it was like that, but I'm not an expert on RPI3.... Then I did various tests and I asked for advice (in this newsgroup) to people who have more experience than me with the RPI (... or at least it is assumed to be so ....) and having failed to find the reasons for the problems I stopped at the 'faulty SD' speech .... and some people shared it ... At this point, only when I go to the remote site will I be able to understand what happened (.. I hope). Surely the first thing I will do is replace the SD with a clone that I had prepared when the system worked well ... Thank you

I think your assessment that some sort of ISP caching is a good one, since apt-get update is simply asking for the Packages file from

formatting link

which we all know exists.

The OP might want to try from the pi account

wget \

formatting link

and see what happens, but I expect another 404. But, I just read that https is not cachable, so maybe

wget \

formatting link

might be just the trick to see if there is some caching going on.

As for your advice, I'm considering using an HD or SSD instead of SD Can you tell me please:

- what kind of HD did you use ? A 2.5" SATA3 with USB adapter ?

- brand, model, capacity ? WD ? Are all brands good ?

- the RPI3 USB port is not capable of powering HD, is it true ? The HD must have its own power supply, right ?....or powered USB hub...

What do you think if I install a Western Digital WDS120G2G0A Green SSD, or SanDisk Plus SSD 120G, or Crucial etc. Does the RPI3's USB port supply an SSD directly ?... or maybe even in this case a powered USB hub is recommended...

What do you think about it ? Thank you

I got a Seagate 1TB external 2.5" hdd for ?50, usb-powered by the 3B+ Pi without problem, that's with the RPi official 2.5A adapter. WD is fine, too, I'm sure (or some will say better). You can set "max_usb_current=1" in /boot/config.txt to double the available power via usb, but that wasn't necessary for me.

Thanks @A.Dumas for the info But from the site

I read these RPI technical specifications: "The USB ports on a Raspberry Pi have a design loading of 100mA each - sufficient to drive" low-power "devices such as mice and keyboards. Devices such as WiFi adapters, USB hard drives, USB pen drives all common much more current and "........." The maximum power the Raspberry Pi can be used is 1 Amp. If you need to connect to the USB device that will take the power requirements above 1 Amp, then you must connect it to an externally-powered USB hub"

Did I misunderstand or did you connect your Seagate 1TB directly to one of the RPI's USB ports ?? I don't understand your phrase: "usb-powered by the 3B + Pi without problem" What is '3B + Pi' ? It is a USB-SATA adapter with independent external power supply ? Thank you
