How to install and configure AdGuard Home for automatic updates and keeping DNS-over-HTTPS running.

To enable AdGuard Home for automatic updates without using snap, or if SELinux is installed, an error occurs: "Cannot download and install the app from snap". So, is there a solution? Switch to Docker.

-

Why switch to Docker when it's just as good as Snap apps? 

• Using Docker containers requires configuring files to access ports, such as Apache2 (if you need separate ports for each website). 

• Snap, however, doesn't require configuring files to access ports; it's ready to use immediately.

-

Which is better for automated app updates: Docker or Snap?

• Snap: Yes, the feature is available immediately in automatic app updates.

• Docker: No, there is no feature for automatic app updates in containers (Watchtower must be installed first). For manual updates, use the `pull image` command to check for the latest version of your app container.

-

App security between Docker and Snap?

• Using Snap is less secure, and IP addresses on the device can be intercepted, reducing the performance of Snap apps; therefore, it's considered unsafe. Consider using VMs securely where IP addresses cannot be accessed. Normally, if SELinux is used for enhanced device security, Snap will be unable to download and install apps. It is highly recommended to disable and permanently uninstall Snap to the junk files.

• Using Docker is considered very safe, and the IP addresses on devices cannot be intercepted. It doesn't degrade application performance because applications can safely use Docker images.

-

You can choose to install AdGuard Home using Docker. However, you will need a web panel to access the app store to download and install apps onto the image, such as: 1Panel.

If you haven't already installed 1Panel, go to 1panel.pro and click "Download" to follow the instructions.

Tips: The screen will ask if Docker is already installed. If not, press "y" to complete the Docker installation.

Considerations after installing 1Panel: For security reasons, enable 2-factor authentication.

-

How can I use Docker and Snap without configuring the app port files for the container?

• Snap: Yes, no app configuration is required. It's available immediately from the Snap App Store.

• Docker: No, you need to manually configure the app files to pull the image. If you don't want to do this, install the web control panel and get the App Store to install the app to the image.

Updated May 20, 2026: Install DDoS Deflate on Ubuntu/Debian to protect devices and reduce internet resource consumption.

DDoS Deflate is a GitHub repository developed by @jgmdev (Jefferson González) - founded 5 years ago, repository age 7 years or longer. DDoS Deflate is now available on Ubuntu/Debian from GitHub @jgmdev, completely free of charge and without any subscription. Provides long-term DDoS protection anywhere! What is DDoS Deflate used for? It protects devices from high internet resource usage by attackers who often randomly guess IP addresses and manipulate website browsing speeds. To use DDoS Deflate as a firewall and avoid conflicts with iptables, using ufw might cause problems. Choosing FirewallD will not cause any issues. DDoS deflate protection is definitely possible with software installed on Ubuntu/Debian. Using a firewall in conjunction can provide even better protection on public, office, and home Wi-Fi networks. Alternatively, use a 4G LTE router, making sure the firewall is enabled. As mentioned regarding DDoS Deflate; for more information on its features, visit: https://github.com...

[Full Step-by-Step Guide] How to share OpenVPN from a TP-Link router to an Ubuntu Server and enable IPTable Forwarding to share a VPN connection with multiple devices without configuring or redirecting an HTTP Proxy (for implementation). - Things you should understand beforehand.

After trying a VPN, my IP address changed. If you're using a foreign VPN, you can choose one from the VPNGate website or search for IPSpeed OpenVPN on Google Search. How to configure an OpenVPN client on a TP-Link router and the steps to enable IP forwarding on an Ubuntu server after completion. Note: VPN Client configuration is only functional on devices during setup on a TP-Link router. For sharing on multiple devices, you will need an Ubuntu Server to enable IP forwarding, which requires configuring IPTables. If you are using Squid Proxy with a VPN accessed from a TP-Link router, you can configure and enable an HTTP Proxy if necessary. Edit the interface and change one of the HTTP Proxy transmission modes. An HTTP proxy handles the exchange of information regarding the device or server address, and then forwards it from the device to access the internet. This is useful if multiple devices are sharing a proxy, but it's not complicated. For IPTables, if an HTTP proxy is not ne...
