The "issue" is when using a remote URI and authn when attempting to connect to the local system when a local URI and usage of pkttyagent was "expected" for local authn. The current bug is: https://bugzilla.redhat.com/show_bug.cgi?id=1374126 which was "forked off" from: https://bugzilla.redhat.com/show_bug.cgi?id=986365 which added the support for pkttyagent processing for "local" authn when the GUI option wasn't available (e.g. when ssh@localhost, run virsh) in order to perform the authn of the user. This is one of those "either" patch 1 or patch 2 will fix the problem, but I really couldn't decide which I liked better. I'm leaning towards the second one only because of the one authn failure; however, I'm not sure I like the escape path comparison to ":///". With only the first patch one would get two challenge/responses before failure, e.g.: $ virsh -c qemu+ssh://someuser@localhost/system list --all someuser@localhost's password: someuser@localhost's password: error: failed to connect to the hypervisor error: authentication unavailable: no polkit agent available to authenticate action 'org.libvirt.unix.manage' $ With the second patch one would get one challenge/reponse before failure e.g.: $ virsh -c qemu+ssh://someuser@localhost/system list --all someuser@localhost's password: error: failed to connect to the hypervisor error: authentication unavailable: no polkit agent available to authenticate action 'org.libvirt.unix.manage' $ Going with #2 restores essentially older (e.g. 1.3.4) processing when the pkttyagent processing loop didn't exist. The challenge/response in either case comes from ssh and is successful; however, code in remoteDispatchAuthList doesn't let a non root user to take this URI option for a local authn/authz because the callerUid is not 0 (root). Although, I suppose it would be possible to check whether the @callerUid was authorized (e.g. part of some group), but that I think "outside" the scope of what the bz is reporting, so I didn't take that route. The reality is the bug is mostly a problem for non UI type processing where providing that ctrl-c to quit isn't as likely/possible.
