I know how you feel. I hope you succeed both with your server and throwing out windows.
Godspeed on your linux journey.

That sucks. But this is a good way to learn.

I use firefox as well, on linux mint, not windows. So if you use windows, that may be the culprit. I haven't used it in a long time so i don't know if that could be the case.

May i be so bold as to ask about how much experience you have with linux?
A basic understanding would go a long way i think.

But to answer your question:
You need to mount the nas drive directly to the lxc running jellyfin, not to the proxmox host.

It always works for me to just paste with ctrl+shift+v directly in the terminal window of the web gui.

The linked repository is unmaintained, and some of the scripts are broken as a result.
The scripts have moved to this repository.
Last time i used then they worked fine.
Try the scripts in the new one, and if they still give you errors let me know and i'll be happy to try and help you.
Also, please don't run scripts from the internet without reading trough them first. Even from a trusted source. You never know what random people could have written in there. 😅

Tteck is unfortunately no longer with us.
The new proxmox scripts project can be found here.

The manual way to embed images is using markdown.

Thanks. 😀
I had to use 4 different sources to make my project work.
It wouldn't be nice to force others to go trough the same amount of trouble when i already have the files.

I made a git repo with the schematic and yaml file for you, if you have any questions feel free to ask.
I may not know the answer, but i'll do my best to help.

I actually have a working'ish prototype of this project laying on my table right now.
It's a 120mm noctua fan being controlled by pwm i relation to the temperature. It also has an oled screen to show temp and fan speed. All controlled trough home assistant via esphome.
I say working'ish because the temp sensor i'm using (dht11) is unreliable and is messing up half the time, so i'm looking into buying a DS18B20 instead.
I'd be happy to share schematics and code if you'd like it.

I have a luks encrypted proxmox machine.
And the easiest way i found to do it was to install debian with full disk encryption and then doing some magic to swap the kernel from debian to proxmox.
Or that's what i think i did at least. I'm no linux magician, i just use it.
On another server i use dropbear to unlock LUKS over ssh. Those two things should be easy to combine.
I took meticulous notes, so i should be able to give you some direction to go if you need some help and can't find a decent guide out there.
