Hi, thought I'd chime in here as just ran into the same issue on debian bullseye. Obtained an oh-so-precious "mycert.p12" file and resolved thus:
Step 1: a) In Firefox ESR: Settings -> Privacy and Security -> View Certificates button (way down at the bottom). b) "Certificate manager" popup window, "Your Certificates", Import button c) Select mycert.p12 file and it appears in Firefox. Step 2: a) In LibreOffice Write: Tools -> Options -> Security, click "Certificate" button under "Certificate Path" This is where it got interesting - there were two selections there: x firefox:default o firefox:default-esr the top one, "firefox-default" was selected and was not working. Clicking "firefox:default-esr" instead, restart LibreOffice Write... fixed. Another important note: After changing the certificate path, it prompts "LibreOffice Write needs to restart in order to take effect. Do this now?" ...which I answered yes, but it did not actually restart. Initially thinking it didn't work. But upon manual restart, it *did* work. Maybe this approach is better since it takes Seahorse out of the loop. Would also be curious to know if Jammy is fixed and/or above works? I'm going to upgrade one of the three debian bullseye systems I did this on successfully, to debian bookworm right now. If anything breaks, I'll be sure to post that here. Hope this helps someone out there. -- 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: Triaged Status in seahorse package in Ubuntu: Triaged Status in gnome-keyring package in Fedora: New Status in seahorse package in Fedora: Unknown 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.
