https://access.redhat.com/solutions/1543343Resolution: Ensure the existence of a polkitd system user & group
Copy/paste the following 2 compound-commands to a root terminal to check for and conditionally create the user/group
getent group polkitd >/dev/null && echo -e "\e[1;32mpolkitd group already exists\e[0m" || { groupadd -r polkitd && echo -e "\e[1;33mAdded missing polkitd group\e[0m" || echo -e "\e[1;31mAdding polkitd group FAILED\e[0m"; }
getent passwd polkitd >/dev/null && echo -e "\e[1;32mpolkitd user already exists\e[0m" || { useradd -r -g polkitd -d / -s /sbin/nologin -c "User for polkitd" polkitd && echo -e "\e[1;33mAdded missing polkitd user\e[0m" || echo -e "\e[1;31mAdding polkitd user FAILED\e[0m"; }
Reset the permissions and user/group ownership for all files provided by the polkit and polkit-pkla-compat packages
Copy/paste the following compound-command to a root terminal to check for and conditionally reset user/group perms & ownership
rpm -Va polkit\* && echo -e "\e[1;32mpolkit* rpm verification passed\e[0m" || { echo -e "\e[1;33mResetting polkit* rpm user/group ownership & perms\e[0m"; rpm --setugids polkit polkit-pkla-compat; rpm --setperms polkit polkit-pkla-compat; }
Reboot
A reboot of the machine will be required to make sure that all changes take affect and that polkit has reconnected to the dbus
shutdown -r now
