From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hello, I yet again come, hat in hand, for assistance from those wiser in the ways of the Linux. I’m having a bit of an issue downloading Jellyfin on my ElementaryOS laptop. I’ve tried all the guide on the first few pages of ddg only to receive errors after entering the comman “ sudo apt-get update “. I get ERR:3 https//repo.jellyfin.org/debian circle Release 404 Not found.

If someone can point me the way I’d be most appreciative

Once you know how to use docker/containerization it'll be the only way you want to deploy applications. Most popular applications will also have good guides on how to setup/config the container, but sometimes you'll need to read up on docker and Linux to figure things out.

Yeah I really need to do more reading. My lack of knowledge on Linux is my main issue I think. Just jumped the gun to Linux like a month ago, played around in elementary for a bit and was like “now is the time to set up my media server”. Prob needed more time, reading, and texting but eh.

I appreciate the advice I’ve been getting here big time!

Some of the commands I use a lot for debugging containers, in case you go down that route:

  • docker run --rm -it --entrypoint bash <image_name>
  • This command let's you enter a docker image with bash so you can test commands and treat it like a temporary VM. Great way to see how the image is setup
  • docker exec -it <container_name>
  • This let's you enter a running container with bash. A great way to inspect why something might not be working or check mounted volumes, etc.

Also docker logs -f CONTAINERNAME to see the log output for non-interactive containers.
