After an accidental deletion of some system files the MacBook Air shows only a flashing files with a question mark. I’ve tried reinstalling the system through Internet Recovery. After choosing Reinstall macOS I get the message „To download and restore macOS, your computer’s eligibility will be verified with Apple”. After a short moment I am presented with „The installer information on the recovery server is damaged”. How can I fix that?
Thank you for your help in advance.

This is a pretty rare failure since the installers are signed. You would want to review a couple things:

In the end - your computer couldn’t get a good image to start the install. This is almost always a network / server issue, but you might be able to fix it moving to a new network, validating the date/time on your Mac before you install the OS or changing the version of OS you request.
