Thank you very much Assia R, the solution you propose also worked for me.
I have two comments to help other people who run into this problem:
1. In my case the problem was because I had to use the latest CLI version on my computer to make it compatible when installing the .ipk file on the LG display from the console, downloading and replacing the CLI folder does the job. update
2. It is important to mention that when the CLI folder is replaced, the installation commands remain in an internal "bin" folder, inside the "CLI" folder, for this reason if you wanted to check your version from your console you would have to execute the command while inside the path that includes your "bin" folder, so that it is recognized as a valid command, I leave a picture of the command and my folder structure.
