[gentoo-user] Failure with cfg-update:* invalid key... try again: bash: readkey: command not found

[Meino . Cramer]

Hi,

after submitting

    cfg-update -u

I got

    * invalid key... try again: bash: readkey: command not found

printed on the screen endlessly.

How can I scuccessfully use cfg-update as before?
What did I wrong?

Best regards,
Meino
