Fix for "the key has expired" warning when installing yubico-authenticator-bin

The package verifies the download using Dain Nilsson's GPG key. If your local copy of that key is outdated, GPG will report it as expired even though the key owner has renewed it on the keyserver.

To fix it, refresh the key:

curl https://keys.openpgp.org/vks/v1/by-fingerprint/20EE325B86A81BCBD3E56798F04367096FBA95E8 | gpg --import

Then rebuild/reinstall the package as usual. The warning will be gone.

Heads up: Version 7.3.1 is not a Linux version. Please check the release notes for platform-specific details before flagging this as out-of-date

@aryklein, They might be overkill to declare, but I noticed that the app wouldn't start in a fresh arch distrobox with only yubico-authenticator-bin installed. I had to install both gtk-3 and libnotify for the application to launch properly.

@gentoofan, I’m not sure they’re mandatory. Why do you think these packages are runtime dependencies? Would anything break if they weren’t included?

Change done @muneoarch. Thanks

To make this package compliant with Arch RFC 0016, could you please rewrite the license field as follows?

license=('Apache-2.0')

The current PKGBUILD is actually missing some runtime dependencies: gtk3 and libnotify. Here's a patch to fix that:

diff --git a/PKGBUILD b/PKGBUILD

For months now I'm seeing the below error. On the GUI it shows up as "Failed connecting over ccid and otp". Using ykman works for retrieving OTP keys, so communication with Yubikey is fine.

Any ideas how to fix this? Some Python dependency needs updating, maybe?

@aryklein: Works fine, thank you
