Package: libpam-u2f
Version: 1.0.7-1
Severity: important
Tags: upstream

Using pam-u2f with sudo (and likely other applications), I cannot interrupt
it when waiting on a U2F device, whereas Ctrl-C works as expected when I am
prompted for a password.

> $ sudo id
> Please touch the device.

Here is my PAM configuration for sudo:

> # /etc/pam.d/sudo 
> #%PAM-1.0
> 
> # here are the per-package modules (the "Primary" block)
> auth sufficient pam_u2f.so authfile=/etc/auth/u2f_sudo cue
> @include common-auth
> @include common-account
> @include common-session-noninteractive


Best,
