Have you tried the 64-bit(arm64) Raspberry Pi OS? The Pi can't run 64-bit apps on a 32-bit OS, but the CPU is capable.
That was a problem that I had at one point and then I then reflashed the 64-bit Raspnberry Pi OS (no longer called raspnbian which I didn't know). When I run uname -a I get aarch64...
The specific error I'm getting is this:
FAILED! => {"changed": false, "errors": [], "module_stderr": "", "module_stdout": "0.18.2: Pulling from dessalines/lemmy\n", "msg": "Error: pull failed with no matching manifest for linux/arm64/v8 in the manifest list entries"}
Lemmy doesn't run on arm atm due to cross-compile issues.
See the PR: https://github.com/LemmyNet/lemmy/pull/2806
it runs fine if you don't cross-compile and build it on the pi itself ( or emulate an arm system using qemu or similar)
I was able to install lemmy just now on the rpi. I used ubergeek77's stuff.
Use ubergeek77's multiarch docker images instead of the official ones. Official ARM support for Lemmy stopped in version 0.17.3.
I saw it but I don't know how to use it.
Replace dessalines/lemmy:0.18.2 with ghcr.io/ubergeek77/lemmy:0.18.2 in your docker-compose.yml file. Do the same for lemmy-ui.
This got me working, but, for anyone who comes across this, the file to edit is lemmy.yml, and you drop in ghcr.io/ubergeek77 for dessalines. The only hurdle once I did that was installing docker-compose on the pi. Unfortunately you can't just install docker-compose with pip3 install docker-compose. Follow these instructions to install docker-compose. https://dev.to/elalemanyo/how-to-install-docker-and-docker-compose-on-raspberry-pi-1mo
Then just run the ansible playbook.
Wow, okay let me try that. I wish you had been around earlier! Thank you so much.
The documentation is kind of a dog's breakfast but you could try building it from source. Note that this is not easy and will require a lot of time and patience. I managed to do it on FreeBSD but never could get it working properly. Lemmy would federate but pictures wouldn't work and I eventually gave up.
I'm going to see if I can get it working on ubuntu 22 first.
