Misformed armored text recover account from another device

Hello, I try to recover account from another device to use in the same, when I select private key and click next y obtain the next message “Misformed armored text” and not to go to the next step. Why product this error?
Thank You.

Hi @javier.juarez

Welcome to the forum! The key has a header and footer with a specific format.

Header from my key:

-----BEGIN PGP PRIVATE KEY BLOCK-----

Footer from my key:

-----END PGP PRIVATE KEY BLOCK-----

Notice the number of hyphens, and the spaces between words.

Typically, if a user saves the file directly from the installation, it’s format is unchanged and can be opened via the GUI later for recovery. However, If the key was copy/pasted, this may have resulted in additional characters, depending on which text editor was used.

Please respond after checking, thanks.
