snapcraft register-key timeout

[Robin Elvin]

I'm trying to follow the instructions for creating an Ubuntu Core model assertion but the register-key command doesn't work:

$ snapcraft register-key kiosk-model-key

Sorry, an error occurred in Snapcraft:
Command '['snap', 'export-key', '--account=EyLgeiBk4chQJ40ljhXjJvmlfdmRnw0C', 'kiosk-model-key']' returned non-zero exit status 1.
We would appreciate it if you anonymously reported this issue.
No other data than the traceback and the version of snapcraft in use will be sent.
Would you like to send this error data? (Yes/No/Always/View) [no]:

Additionally trying to get more verbose output both turns up the verbosity and exits saying no such option:

$ snapcraft register-key --verbosity=trace kiosk-model-key

NOTE: This is using a SSH session. I have executed `export GPG_TTY=$(tty)` in the session beforehand.
Running the command directly in a GUI shell shows the key passphrase window and it works.

[Callahan Kovacs (mr-cal)]

Are you working in an environment with gnome-keyring?

Based on your comment about being in an SSH session, do you think it is similar to this? https://forum.snapcraft.io/t/snapcraft-login-command-not-working/40013/4

[Robin Elvin (elvintech)]

No, I am not using gnome-keyring.

Yes, I believe it is the same issue - there is no cli prompt fallback so the command times out waiting for the key to be unlocked.

[Callahan Kovacs (mr-cal)]

I see, can you provide your OS, desktop environment, and the keyring you are using?

I'm glad you reported this. I was focusing on gnome-keyring but now we will need a more generic solution.

[Robin Elvin (elvintech)]

I am using Linux Mint 21.3 Virginia, desktop environment Cinnamon.

Can you clarify what you mean by "keyring"? As far as I know this is using a new GPG config created by snapcraft. If you can tell me how to check I'll update this ticket.

Thanks

[Callahan Kovacs (mr-cal)]

Thanks. By "keyring" I mean the system that stores secrets like GPG keys. The first attachment shows the keyring in the system settings.

I just installed Mint Linux 21.3 (Cinnamon) and reproduced your issue. It looks like Mint uses gnome-keyring is used by default (see second attachment). Note that 'gnome-keyring' is a mostly generic keyring that doesn't have much to do with gnome.

So it looks like we can still target a solution that on focuses on gnome-keyring.

Ok, that's great thanks. Sorry for the misinformation about gnome-keyring! Checked and confirmed it is what I have on my installation.

No worries and thanks for the report.
