CCing the polkit folks for their input. This bug is in regards to two polkit
agents being installed in testing/unstable now that xfce-polkit has migrated to
testing. They cause an error message to appear when both try to start after
logging into the desktop.
I think that xfce-polkit is pulled in due to the virtual package
polkit-1-auth-agent. I found two packages that depend on this virtual package
and one that recommends it with a fresh xfce install but there may be more.
nm-connection-editor and network-manager-applet depend on this virtual
package,. Thunar recommends it. Xfce4 recommends mate-polkit directly.
Is it possible that the virtual polkit-1-auth-agent dependency of the
network-manager packages is resolved first and xfce-polkit happens to be
picked, and then mate-polkit is also installed to satisfy the recommends for
xfce4? This is all guessing; I don't know how dependency resolution works in
apt in these sorts of situations.
Both these packages seem to do about the same thing, so I think choosing one
and making sure only one is installed would be fine. This seems best decided by
the xfce maintainers.
