The deepin community will release system updates for deepin 25 Alpha this afternoon. While this update includes multiple functional optimizations and issue fixes, users who have not executed the critical fix script in advance may encounter upgrade failures due to system configuration and component compatibility issues.

To ensure a successful upgrade, DO NOT proceed immediately after detecting the update. Follow these steps:

Step 1: Check System Updates

Open Control Center → System Update. Wait for the update check to complete. If the system shows "Your system is up to date," check again later.

If updates are detected, DO NOT upgrade yet. Proceed to the next step. Users who check updates via apt update must also execute the following operations before running apt dist-upgrade.

Step 2: Manually Download and Execute the Fix Script (Critical!)

1、Download the script and grant execution permissions:

Download the attachmen upgrade_fix.zip from this post to a local directory (e.g., "Downloads") and extract it to get upgrade_fix.sh.

Then open the terminal and run these commands (adjust paths as needed):

cd /home/Replace_with_your_username/Downloads  # Modify if saved elsewhere

Or right-click in the corresponding download directory and open a terminal to execute the following command to authorize the script:

chmod +x upgrade_fix.sh

2、Execute the script:

Run:

sudo ./upgrade_fix.sh

The script will:

• • Update critical components (deepin-immutable-ctl, dde-control-center, etc.).
  • Clean redundant kernels/snapshots to free /boot space.
  • Reboot the system immediately after completion.

Step 3: Perform System Update

After rebooting:

1. Go to Control Center → System Update → Update Now and follow the prompts.
2. Reboot again to finalize the update.

Important Notes

1. If the script reports errors or exits:
   ◦ Verify the script path is correct and ensure execution permissions are granted (chmod +x upgrade_fix.sh).
   ◦ Alpha users who haven’t updated since initial installation are most likely to encounter this issue. Regularly updated systems are unaffected.
   ◦ If the error persists, wait a few hours and recheck for updates (ensure latest patches are delivered) before retrying.
2. Reboot immediately after script execution to activate upgraded components.
3. After completing the system upgrade, perform a final reboot to fully apply all updates.
