Today I upgraded libreoffice via PPA from version 7.1.2 to version 7.1.4 where the digital document signature function stopped working. When informed about the resolution of this bug in version 7.1.2, I didn't find the date of update of libreoffice from version 6.4.7 to 7.1.2 in ubuntu version 20.04, so I decided to test version 7.1.2 via PPA and it worked. With the update via PPA this function was now stopped working with version 7.1.4. Is there any relationship in ubuntu regarding these libreoffice versions?

However, the key is not listed in the list of certificates shown following the menu File - Digital Signatures - Digital Signatures... - Sign Document..., after, e.g., creating and saving a document on LibreOffice Writer.
