Join me in this comprehensive guide as we set up Nextcloud in an LXC container using Docker Compose on Proxmox. I'll walk you through each step, ensuring you can follow along and get your private cloud up and running in no time.

📝 Commands used in the video:

```bash
sudo apt-get update
sudo apt upgrade
sudo apt install curl
sudo apt install docker.io
sudo apt-get install gnupg


Overwrite the existing Docker GPG key just in case
curl -fsSL https://download.docker.com/linux/ubu... | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

Add the Docker repository with the correct Ubuntu version codename
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu jammy stable" | sudo tee /etc/apt/sources.list.d/docker.list

Update your package database
sudo apt-get update

Install Docker, Docker CLI, containerd, and Docker Compose
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose

sudo systemctl start docker
docker-compose up -d
docker exec -u root nextcloud chown -R www-data:www-data /var/www/html/data

sudo systemctl start docker

sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io

sudo systemctl start docker
