Yup, it works great. I actually did it myself when migrating from a centos to debian host. Worked first try, no issues (except one thing that was already broken but I didn’t know because I hadn’t accessed it recently). Containers are great for this.

This. Cloud-init, or autoinstall for Ubuntu, to get the install done, then use ansible for anything more.

Bind mounts. I’ve never bothered to figure out named volumes, since I often work with the contents outside Docker. Then I just back up the whole proxmox VM. (Yes I’m aware proxmox supports containers, no I don’t plan to convert, that’s more time and effort for no meaningful gain to me.)

You can restore that backup to a new VM. I just make sure it boots and I can access the files. Turn off networking before you boot it so that it doesn’t cause conflicts.

The issue is not encryption, it’s the unauthenticated API. People can interact with your server without an account.

The DJ is the artist. Each set is an album with one track. What’s broken about that?

Jellyfin should be fine. Why do you say it breaks it?

Yes, you can convert RAID1 to 10. At least in theory, your controller has to support it. Check the system documentation. TrueNAS ought to.

But gradual upgrades in general are rarely supported. The recommendation is always to do a complete array replacement.

Don’t put important stuff in /tmp. Put it in /opt or something.

If you use the ISP one, you’ll rapidly find you can’t configure it to do what you want. Run your own, lock it down, and keep it up to date.

The apps you list need decent gpu and gpu doesn’t virtualize well.

That’s not really true any more. To actually get it working, especially sharing a GPU between multiple VMs, is finicky, especially if you’re not using the very narrow supported configuration and expensive enterprise hypervisor features. But it is possible, and you can find plenty of articles from people who have gotten it working.

But I still wouldn’t recommend it. I’d give one whole GPU to one VM with PCI passthrough, and let multiple users remote in. Hopefully the apps support that.

Depends on how you want to define “securely”. A sufficiently motivated attacker could attack the remaining encrypted data, either through brute force or exploiting a weakness in the algorithm.

Students, as in you’re a teacher? Talk with your school’s IT department first.

No idea, you’re the one that bought it. I did the same thing for a few years and never bought a plex pass.

What we should be asking is why “selling a product” is no longer a business model.

Because they’re not selling a product, they’re selling an ongoing service. They run the relay servers, and those cost money every month.

He didn’t say he can’t, he said “but the site says!”

Yeah I know what the site says, I linked to it, I can read (usually). You know what I do when I want to do something? I try.

I don’t know why people ask for help and refuse to listen when it’s given.

You should be able to add the repo and install the packages anyway. If it doesn’t work, give a description of the behavior including errors or logs.

If you really access them that infrequently, are they actually worth keeping?

Prove it with data, else you’ll just be blindly throwing money down the drain.

And you’ve verified that the DNS record has the correct IP address? I would check the web server config to make sure it will respond to that name. See if there is anything in the access or error logs.
