I have installed VirtualBox on my Mac laptop, and built Ubuntu 19.04 guest VM - but had issues with everything that requires HTTP/HTTPS access. Eventually, I came across this post - which matches the issue I have and explains why that's so...
To have another look at it, I searched for other ways (other than using SSL import utility) - and came across 'pk12util' which "supposed to" be able to import PK12 certificates (under normal circumstances). Using this utility, I'm getting "SEC_ERROR_LEGACY_DATABASE: The certificate/key database is in an old, unsupported format" errors: vpogrebi@vpogrebi-VirtualBox:/usr/local/share/ca-certificates$ sudo pk12util -i cacert.pem pk12util: function failed: SEC_ERROR_LEGACY_DATABASE: The certificate/key database is in an old, unsupported format. vpogrebi@vpogrebi-VirtualBox:/usr/local/share/ca-certificates$ sudo pk12util -i IDEXX-NewPKI-SHA2-Chain.crt pk12util: function failed: SEC_ERROR_LEGACY_DATABASE: The certificate/key database is in an old, unsupported format. vpogrebi@vpogrebi-VirtualBox:/usr/local/share/ca-certificates$ sudo pk12util -i dockercom.crt pk12util: function failed: SEC_ERROR_LEGACY_DATABASE: The certificate/key database is in an old, unsupported format. Hope this can help resolving the issue; but in the meantime - it seems that I have to completely delete Ubuntu 18.04 VM and start all over using older (16.04 ?) version. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to seahorse in Ubuntu. https://bugs.launchpad.net/bugs/1771880 Title: Seahorse unable to import pkcs12 certificates 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.
