First off I am new to Linux, writing any sort of code, and new to docker and tailscale. The first few containers I got running fine on my tailscale network were premade tailscale sidecars so I didn't create the compose and env files myself. This is my first attempt at doing a container without premade files, and please just don't just paste the fixed file show me what I did wrong so I can learn.

The docker container I'm trying to run is called Cannery. When I run sudo docker compose up even though I get an error it does show up online in my tailscale machines list as cannery.funny-name.ts.net but of course connecting to it fails.

The error I am getting is:

ERROR! Config provider Config.Reader failed with: app-cannery | ** (RuntimeError) No hostname set! Must be the domain and tld like `cannery.bubbletea.dev`.

Here is my docker yml file if you could read it and show me where I am messing up. Thanks for any help!

I don't need the app's ability to send email notifications so bypassing this part doesn't effect functionality at all for me.

EDIT: Found the fix! in the folder etc/apt/sources.list.d I just had to edit a line in the file additional-respositories.list and change the name from zena to noble. Then the tailscale install command worked perfectly and I have my linux mint machine connect to my tailnet now!

So I'm running Docker Compose and Karakeep on a new little Linux Mint 22.3 "Zena" machine I got going recently. This is my first time both with Linux and selfhosting. When I try to run the followinng command from Tailscale's download page:

sudo curl -fsSL https://tailscale.com/install.sh | sh

Tailscale won't install due to an error about a release file not found. Here is what the command above displays in my terminal:

Reading package lists... Done

E: The repository 'https://download.docker.com/linux/ubuntu zena Release' does not have a Release file.

N: Updating from such a repository can't be done securely, and is therefore disabled by default.

N: See apt-secure(8) manpage for repository creation and user configuration details.

I posted in the r/Tailscale subreddit and someone told me that this looks to be a docker repository issue and not Tailscale, and that I need to clean up the docker apt source first for Tailscale to install.

So what is my fix here? Any help is greatly appreciated.
