I participated in that with a ProLiant server with 540GB RAM and no GPU.

Is that just a model, or is there actually a display in the middle that does something?

I just use Auxio on Android or GNOME Music on Linux to listen to my downloaded files, and sync them via Syncthing.

Try Heliboard! It allows you to customise that

What are the current logos then? Did Linux’s change?

Oh no, only 3 more years

Can this be self-hosted, so you’re not sending data to a third party service?

When they said Android I assumed they meant degoogled or a custom ROM, but it’s good to point that out I suppose.

You should get a Fairphone and use a degoogled custom ROM. If you really want to get away from Google at the expense of some functionality, you can try a Linux ROM, but I’d recommend one based on Android such as Lineage OS. The benefits are mostly freedom adjacent. You have the freedom to run any app you want, whether it’s from the app store or not. You have the freedom to use any browser engine you like, and download extensions to Firefox. You have the freedom to root your device and make simple full backups of your device to any local storage that you own by accessing the root storage folder. You have the freedom to use apps like Rethink DNS to block ads device-wide, and there are generally a lot more FOSS apps written for Android than iOS as you don’t have to jump through all the hoops of the app store to make your apps available for others.

I would select CC-BY-SA so that if they share it they have to use the same licence

I use Krita for raster, but Inkscape is the best for vector

I tried what I said, reinstalling to see if it still had internet. It did not. Therefore I went into a rabbithole of trying to rule out specific things of why it was working then but not now, and I still have no idea why it was working then, but I have plugged the Ethernet powerline into a new, more inconvenient, plug socket, and the wired internet is mostly working! I can still access most sites, but Firefox won’t connect to addons.mozilla.com or accounts.firefox.com. Idk if that’s a Firefox issues or a network issue, but it’s mostly working now, which is great!

Fairphone 5 isn’t old. It’s a fairly recent, midrange phone

Linux phones do exist, I was saying that you could use Waydroid on those devices (although you can also use it on Linux Desktop), such as postmarketOS on eg a Fairphone 5.

You can already, Waydroid exists

Hmm. One way to check multiple options at once is to try the install again and see it internet is still present when installing the OS, as it was before. If it is, that would rule out a hardware issue.

Why is that? I applied the change, and restarted the Ethernet connection, but I still don’t have internet

Here are the network settings

I tried changing the IP in manual settings, I’m not sure how I ping an IP, I assume it’s a command that I don’t know, but as the screenshots show, accessing a website didn’t work. I saw an IP in the startup menu and tried that but it didn’t seem to work

Did you want a specific part of network settings, or is this helpful?
