Fixing the 'Store App Not Found' Error: How to Downgrade CasaOS to Version 0.4.7


CasaOS, a lightweight home cloud system, recently released version 0.4.8, bringing several updates and improvements. However, some users have encountered a “Store App Not Found” error when trying to install custom Docker Compose setups. This error is linked to the latest update requiring the use of the latest tag for operations. If you’re facing this issue and looking to revert to a version that supports custom Docker Compose without errors, this guide is for you. Here, we’ll walk you through downgrading CasaOS to version 0.4.7.

Why Downgrade?

Downgrading to version 0.4.7 can help avoid the “Store App Not Found” error and ensure your custom setups work seamlessly.

Before starting the downgrade process, it’s crucial to safeguard your data. Ensure you have a backup of important directories. This precautionary step is vital to prevent any loss of data or configurations.

Step 1: Backup Your Data

Make sure you backup anything important!

  1. Backup /DATA/AppData: This directory contains your app data and configurations. Backing up this folder ensures you can restore your apps to their previous state after the downgrade.
  2. Backup /var/lib/casaos/apps: This directory holds CasaOS docker compose files.

Step 2: Downgrade CasaOS

After ensuring your data is safely backed up, the next step is to SSH into your CasaOS server and initiate the downgrade process. Here’s how:

  1. SSH into Your CasaOS Server: Use your preferred SSH client to access your CasaOS server. This step requires you to have SSH access and the necessary credentials.
  2. Run the Downgrade Command: Execute the following command in your terminal:
wget -qO- | sudo bash

This command fetches and runs the downgrade script from CasaOS’s official repository. It will automatically downgrade your CasaOS to version 0.4.7.


If the command doesn’t work, you can show more output during the download process with:

wget -vO- | sudo bash

What to Expect:

  • The downgrade process should complete without errors, reverting your CasaOS installation to version 0.4.7.
  • After the downgrade, you can proceed to use custom Docker Compose setups without encountering the “Store App Not Found” error.

So I tried this in the casaos terminal. The first attempt said command not found. Did it again and it started to run. I don’t think it quite completed but gave a message about apps couldn’t be loaded but I figured that might be because it’s still in the middle of doing the command. At some point I refreshed and now it says site cannot be reached. Has been that way for about 10 minutes now. Any advice on how long this should take? Or is the server just gone?

Actually I got it figured out! I had no idea what SSH was or how to do it. did some googling and figured out that it’s through command prompt haha. Redid the 4.7 install and it’s back up.

Awesome glad you got it working.
