  • Use -C instead of -c. See if the bug is fixed like this. Quote the email as well.

Probably a detail in the command.

Instead of using -c (c letter in lower case) use -C (uppercase letter C). Also correct the command and leave the e-mail in quotes. The final command should look like this:

ssh-keygen -t rsa -b 4096 -C "[email protected]"
