Safe to downgrade to: a release before 42.0.0

1. Check installed version

npm ls electron

2. UPGRADE to 41.10.6

npm install electron@">=41.10.6"

3. If no update is available yet, DOWNGRADE to a release before 42.0.0

npm view electron versions npm install electron@"<42.0.0"

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
