I haven’t even got Lemmy running yet, I’ll still trying to compose Docker.

I’ve never used docker before. It’s a strange newfangled technology I don’t understand. Back in my day you either used apt-get, or you compiled it yourself. I want to learn, and I thought installing Lemmy would be a good learning opportunity, but I’m finding myself chasing my own tail instead. My docker version is Docker version 24.0.2, build cb74dfc, and google is seeming to indicate that’s docker engine. I can’t see how docker desktop would be trying to run on ubuntu.

Cannot autolaunch D-Bus without X11 $DISPLAY

Looks like you need more skills to be able to install it

I used to be with ‘it’, but then they changed what ‘it’ was. Now what I’m with isn’t ‘it’ anymore and what’s ‘it’ seems weird and scary. It’ll happen to you!

Thanks. I get the same error even with pictrs image set to docker.io/asonix/pictrs:0.5.4

My server is running the default ubuntu image from Oracle Cloud. I don’t think it has X server installed.

I’m starting with sudo docker compose up -d and my docker-compose.yml is:

Thanks. Do you know what I could have done wrong? I’ve looked through all the config files and there’s nothing about a display in them, unless you count lemmy-ui
