The package description doesn’t make sense:
“The ukui-polkit package supports general authentication and biometric
authentication that the service is provided by the biometric-auth package. “
^^^^^^^^
The problem is the words I’ve highlighted. I suspect what’s intended is:
“The ukui-polkit package supports general authentication, and biometric
authentication provided by the biometric-auth package.”
But I’m not actually sure! It would be good if the description were
rewritten to be comprehensible.
