Signature isn't selected when trying to sign during export of PDF-file from Libre Office

[HeRo]

Hi!

I have an Enigmail PGP signature that I use in Thunderbird under Ubuntu Linux.
In Libre Office I can use it to sign (and encrypt) an ODT-document.
But when I try to use it during export of a document as a PDF document something goes wrong. In the 'PDF Options' window on the 'Digital Signature' tab, I click on the 'Select' button and get the 'Select Certificate' window. My signature is already selected (it's the only one present). I now click on 'Sign'. The window closes, but the signature isn't shown in the field called "Use this certificate to digitally sign PDF documents:". So when I press the 'Export' button, I get a "signature generation failed" error message, and export of the PDF file fails.

Can anyone help me?
Thank you.

Best regards,
Henrik

I don't understand exactly. In which software do you try to export a PDF? In LibreOffice?

[HeRo]

Yes, in LibreOffice Writer. Version: 6.0.7.3.

I'm sorry, but that's not related in the slightest way to Enigmail. I'd suggest you ask for support with the LibreOffice guys.

OK. Sorry for the inconvinience.
