There’s this meme of ‘why is ChatGPT expert on everything but the area I have knowledge of’.

That’s just Gell-Mann amnesia applied to chat bots.

There’s a ~/.docker/config.json. In that there’re some auths, with keys https://index.docker.io/v1/, https://index.docker.io/v1/access-token, and https://index.docker.io/v1/refresh-token, and then there’s "currentContext": "rootless".

There’s ~/.docker/contexts/meta/[a long hex string]/meta.json, with {"Name":"rootless","Metadata":{"Description":"Rootless mode"},"Endpoints":{"docker":{"Host":"unix:///run/user/1000/docker.sock","SkipTLSVerify":false}}}.

The only file in /etc/docker is key.json.

I never set one up myself, and this 11 year-old thread implies that Raspbian doesn’t have one set up by default. It is a very old thread though, so could be wrong.

edit: this is more recent and also says Raspbian doesn’t have DNS caching by default

edit: oh, and in my router’s configuration:

• Primary DNS Server:9.9.9.9
• Secondary DNS Server:1.1.1.1

I’m happy to keep it public if only for the off chance that if we find a solution it might some day help someone else with the same issue. The thread’ll fall down in the rankings naturally over time anyway so I wouldn’t worry about polluting anything for people not actively seeking it out.

I’m not 100% sure how to find the OS version, but uname -a outputs [...]6.12.25+rpt-rpi-v8[...]. /etc/os-release contains “Debian GNU/Linux 12 (bookworm)”. It should be whatever was latest as of a month or two ago when I installed the OS fresh.

DHCP server as in on my router?

Still get exactly the same error.

Do you have no ipv6 address now in ip addr

Just comparing it by eye, there’s no change.

net.ipv6.conf.all.disable_ipv6 = 1

But disabling IPv6 in the OS should fix it

I’ve already followed the instructions I could find to do that, but it didn’t work. Either disabling IPv6 isn’t the solution, or the instructions for how to disable it are incomplete. (You can see comments elsewhere in the thread for more detail.)

Sorry, maybe I should have explained every single step I tried in the body of the original post. I didn’t, partly because there were just too many and partly because I forgot which methods I had tried and which pages I had visited. But that page is one I’ve seen already.

It mentions to “blacklist” the module in a file that doesn’t exist. In fact, in a file that’s in a directory that doesn’t exist, which makes me very sceptical about the later claim that creating that file will fix it. /etc/modules-load.d exists, but not /etc/modules.d. I did already try the final suggestion to add that line to the end of /boot/firmware/cmdline.txt though. No luck.

I think the fact that it’s 6 years old is probably a big part of the reason it didn’t help. Files and directories have moved around. The suggestions in that post are literally just “do this” without any underlying explanation of what it’s doing that could lend to further investigation of the more modern way to do it.

It’s like if you asked why the top gear in your car isn’t working and gave the model of car and engine type and gearbox

Except if I try and access the same domain using curl, it works fine. For some reason, Docker specifically is what’s failing.

Yes, that is what I am here seeking help with.

If you want to mention him, I won’t try to stop you (not that I could if I wanted to). For me though, I’m pretty sure he’s already aware of the existence of !notjustbikes@feddit.nl so he has the resources to follow threadiverse discussions of himself if he wants, and I’d rather leave it in his hands to control that rather than have it thrust upon him.

I’ve never had that problem. Are you running it on the latest version of the YouTube client that Revanced Manager says it supports? Or trying to run it on an unsupported version of the YouTube client?

Revanced is the native YouTube app with free access to the features normally in Premium like removing pre/midroll ads and picture-in-picture, in addition to extra add-ins like Sponsorblock, Dearrow, the choice to either remove Shorts entirely or automatically play them in the regular player, etc. It also works with your YouTube account, so you can read and write to your regular playlists, view your subscriptions, etc., and any changes you make will be immediately reflected on your logged-in web browser.

In much simpler terms:

Think of an IP address like a street address. 192 My Street.

There might be multiple businesses at one street address. In real life we address them with things like 1/192 My Street and 2/192 My Street, but there’s no direct parallel to that in computer networks. Instead, what we do is more like directing your letter to say “Business A c/o 192 My Street”. That’s what SNI does.

Because we have to write all of that on the outside of the envelope, everyone gets to see that we’re communicating with Business A. But what if one of the businesses at 192 My Street is highly sensitive and we’d rather people didn’t know we were communicating with them? @bjoern_tantau@swg-empire.de’s proposal is basically like if you put the “Business A” part inside the envelope, so the mailman (and anyone who sees the letter on the way) only see that it’s going to 192 My Street. Then the front room at that address could open the envelope and see that the ultimate destination is Business A, and pass it along to them.

I just took a really quick look at it, but under Importing data from Nominatim it says “-country-codes allows to filter the data to be imported by country. Set this to a comma-separated list of two-letter language codes.”

That’s a different section from the Importing data from a JSON dump section, which is where it only mentions -country-code. But even that does seem to suggest it takes “all the parameters of an import from a Nominatim database”. So it seems like either the documentation for one of them is wrong, or both are lacking (because in fact both the singular and plural work).
