“Error installing”.

This was an update. The system has been running for at least a year. The system seems to be operational.

I did have some significant Internet connectivity issues so perhaps it’s related to a download problem or corrupted package. I’ve gone in and manually updated but it says no updates available.

I don’t know if I should be concerned or not. Please let me know.

Thanks in advance.

Yes, this error indicates a network connection issue during the update check.
Nothing to worry about
