Well, after filling the report on GitLab, as suggested in comment #15, I receive the following statement from there:
Andre Klapper 💬 @aklapper · 14 hours ago Developer You are using a version that is too old and not supported anymore by GNOME developers. GNOME developers are no longer working on that version, so unfortunately there will not be any bug fixes by GNOME developers for the version that you use. By upgrading to a newer version of GNOME you could receive bug fixes and new functionality. You may need to upgrade your Linux distribution to obtain a newer version of GNOME. Please feel free to reopen this bug report if the problem still occurs with a recent version of GNOME (3.32), or feel free to report this bug in the bug tracking system of your Linux distribution if your distribution still supports the version that you are using. --- I may well be wrong (I'm a lawyer, not a developer) but I understand that this issue is an "Ubuntu bug" not a "GNOME bug", as it apparently just happens in Ubuntu 18.04 LTS, which is supposed to be supported for 5 years until April 2023. Nevertheless, the solution was marked herea mere "wishlist". I assume no one will spend time trying to fix it, despite de lifespan support of Ubuntu 18.04 LTS is supposed to last 4 years more. That's sad! -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-keyring in Ubuntu. https://bugs.launchpad.net/bugs/1771880 Title: Seahorse unable to import pkcs12 certificates Status in seahorse: New Status in gnome-keyring package in Ubuntu: Confirmed Status in seahorse package in Ubuntu: Confirmed Status in gnome-keyring package in Fedora: New Bug description: seahorse 3.20.0-5 / gnome-keyring 3.28.0.2-1ubuntu1.18.04.1 / Ubuntu 18.04 LTS / GNOME 3.28.1 When trying to import a certificate into seahorse/gnome-keyring on Ubuntu 18.04, seahorse GUI application shows the 'import' button greyed out, while mouse hovering the "import" button shows the message "Cannot import because there are no compatible importers". This problem doesn't occur on Ubuntu 16.04 LTS (Seahorse 3.18.0), as I've just tested on my wife's laptop, but happens in my Laptop with Ubuntu 18.04 LTS (Seahorse 3.20.0-5). Because that problem, it's not possible to digitally sign documents with LibreOffice.
