Comment 37 for bug 1771880

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?! ...
