Explanation:
 
This will happen when a version of AXTU that is lower than axtu-1.4.0-1AXS3 is used and when Redcastle is enabled. Redcastle is an application that secures the OS. The rules that Redcastle follows prevent the complete update of AXTU. AXTU needs 7 packages to run, including axtu-gui and axtu-tui. When AXTU updates itself, those 2 packages are blocked by Redcastle when it is enabled. AXTU is then partially updated and does not function anymore.

Solution:
 
Step 1: Set Redcastle to “Disabled” or “Warning”. Please refer to the Redcastle manual.
 
Step 2: Please visit our TSN website and download the latest version of AXTU.
