The keys I was trying to import into Seahorse were located in an encrypted container (mounted, obviously). As I cannot influence (or haven't learned how to influence) the standard file modes when mounting said container, they all had 0700 as file mode, including the .pub files I had generated based on that AskUbuntu answer.
Once I copied them over to ~/.ssh they popped up immediately in Seahorse. So it's definitely not the file format that is/was the issue here. Either it's the file mode, a certain expectation of what it ought to be or it's the fact that the keys I was trying to import weren't in ~/.ssh; or something else altogether?! ... -- 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 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).
