I'm new to Proxmox and have limited experience with Docker. I'm trying to install Docker to run FrigateNVR based on a guide I found, but I've hit a snag while installing Docker and Portainer. I see a couple of errors pop up during the process:
- After confirming the installation of Portainer, I received errors related to some commands failing to execute properly. The shell exits the installation, but it seems Docker is installed; however, I'm unable to connect to Portainer.
- I've attempted this installation three times, and every time it fails. Can anyone help me understand what these errors mean? Am I missing something in my setup?
Additionally, I found another error in the Docker LXC logs indicating a volume doesn't exist. Any insights would be appreciated!

I encountered a similar error while trying to install Docker from the same guide. I had to update the script’s URL too. Some others have pulled it off recently, but keep in mind those installations can get tricky.
If you're facing issues with LXC, I suggest spinning up a regular VM instead. You won’t run into the same problems, and it should make everything smoother.
You might want to raise this issue with the developers of the script you're using. Generally, using Docker within LXC isn't ideal; it's better to run it in a dedicated VM to avoid complications.
Installing Docker inside an LXC container isn't officially recommended by Proxmox. You may want to consider contacting the creators of the community scripts for support, or try using a more officially supported installation method instead. Check out their discussions on GitHub for more help.
Docker version 29 has been known to break several things, so it's possible that's affecting you too. Overall, for the best experience, running Docker in a Debian server VM is advisable. Also, steer clear of Docker 29 for now since it’s causing problems with Portainer.
