Is yours SG-29CCRPI3DDC7? If so, there was a problem fetching the repository indexes. You can also see it in your screen shots where in the upgrade log there are lines like
W: Failed to fetch https://sensorgnome.s3.amazonaws.com/dists/testing/InRelease Temporary failure resolving 'sensorgnome.s3.amazonaws.com'
Please ensure you have a good internet connection and try again. If you see the same type of errors try the check or sg-update again. I hope this helps!
