During the decompression and therefore installation of the directory artifact the return value is not checked. If the decompression fails (e.g. due to size constraints) the artifact install process continues in the same way it would for an successful decompression. This can leave the system in a corrupted state with a partially installed update. This change fixes the issue by explicitly checking the return value of the decompression process and returning an error code in case of a failure.

I think this won't work as intended because set -e is active. It will simply stop at the tar command once there is an error, because it's not part of a conditional, and won't continue to the next line.
I can't really see the problem with the previous code though, it looks correct to me. ret is being set, and is returned, as it should. The only thing missing is a more descriptive message. Are you saying this didn't work correctly for you?

Here too: This code will never be reached because of set -e.
