Can't read QR-codes in wayland

[traffic-light]

• Yubico Authenticator version: V5.1.0
• Operating system and version: Arch linux with KDE, using wayland as window magager
• YubiKey model and version: Yubikey 5 nfc
• Bug description summary: Can't read QR-code from Xwayland window

The application runs in wayland but firefox and chrome runs in Xwayland (X11 server of wayland)

I don't think there is an easy (if there is) fix for it. But I wanted to let you guys know.

(didn't find a dirty fix to force run it in Xwayland...)

JonnieCache did look further into it. His post:

In my testing I've found that yubico a
uthenticator runs under xwayland, and so does chrome. Firefox runs under native wayland. QR code scanning doesnt work from either browser.

Firefox is 97.0, Chrome is 98.0.4758.80, running ubuntu 21.10.

Ah. so it's completely a wayland issue ;-)
Thanks for looking into it @JonnieCache

@traffic-light Is the issue solved by that reply? If so, can this be closed?

[traffic-light]

I don't think it's really resolved. There is no solution ;-)

But I think it's just a specific windowmanager issue...

[JonnieCache]

The app needs to be updated to use the new wayland screen capture api, something like this.

Beyond my ken I'm afraid.

I just hit this problem and used the following workaround on a site that only had the qr code and did not display the secret key:

• Save the image to a file using the web browser.
• Use the zbarimg program that is in most linux repositories to print the contents of the qr code.
• Delete the image file after setting up the yubikeys.

Yubico Authenticator 6.0 has now been released and uses a new codebase. As such, this issue has been marked with the legacy label, and will be automatically closed in 7 days. If this issue is still relevant to Yubico Authenticator 6, please comment on the issue saying so, and it will be kept open (or be re-opened). Sorry for the inconvenience!

I don't believe this works under Yubico Authenticator 6.

@schmitmd This should work in version 6 on Wayland, but it requires the gnome-screenshot tool to be installed. We mention it here: https://github.com/Yubico/yubioath-flutter/blob/main/resources/linux/README.adoc but I'll make sure we also put it in the main README.

gnome-screenshot i installed but didnt work still

the error is:

{"status":"invalid-command","message":"Invalid parameters: Unable to capture screenshot","body":{},"kind":"error"}

im using the flatpak version of Yubico Autenticator:

Yubico Authenticator com.yubico.yubioath 6.1.0 stable flathub system

[dainnilsson]

My guess would be that this is caused by the Flatpak sandbox and permissions required to run an external command (gnome-screenshot).

The flatpack package of Yubico Authenticator is not maintained by Yubico, so I would suggest opening an issue here instead: https://github.com/flathub/com.yubico.yubioath
