DCU-CLI.EXE (5.4.1) issues, /applyupdates stopping seeminly randomly

Issue: Dell Command Update (Command-line version) "/applyupdates" has been cancelling midway through and not finishing the downloads/installs.

 

This has been an issue since around the February 21st. Our script which download/install drivers for Dell computers has been cancelling in the middle of installing drivers. We know this by analyzing the log created by the "/outputLog" command.

 

The log basically ends suddenly and does not give us a proper summary at the bottom of it (which usually includes execution time and error codes. The last line of the log would look like this "[2025-02-28 13:16:18] : Installing updates (7 of 8). Update Name: Intel Graphics/Arc/UHD/Iris Xe Graphics Driver  "

 

It has affected hundreds of our machines. No matter the state of the computer (old/brand new), the OS version, the model, ect... The only common variable found between all the affecter computers is the fact they are on 5.4.1.

No changes on the script we use has been made anywhere near the time of this starting so I am fairly certain this is not on our end. Those scripts have been used for months on thousands of machines with no issues.

Typically, when encountering this issue, restarting the computer seems to work as the log following the execution of the script on a restart shows proper installation of drivers.
