Failed to sign the flight plan release as the Captain. The First Officer and I elected to bypass the ramp office and computer terminals to comply with new COVID-19 recommendations. My normal habit pattern is to print out a hard copy of release. We elected to go totally electronic and brief the flight utilizing  our individual ipads. I failed to verify that the release was properly electronically signed prior to departure.A break in normal habit patterns and multiple distractions and interruptions in the process.Recognizing the break in habit patterns and recognizing the interruptions and their potential in committing errors.
