Newly installed Oracle Linux 6.8 (actually a RHEL/CentOS 6.8 release underneath), yum install xorg-x11-xauth, xauth list , xauth generate, all xauth commands involve $HOME/.Xauthority file fail with xauth: error in locking authority file /root/.Xauthority. I have these 3 files:
[root@oracle11 ~]# ll .Xauthority*
-rw-------. 1 root root 0 Dec 7 09:45 .Xauthority
-rw-------. 2 root root 0 Dec 7 09:45 .Xauthority-c
-rw-------. 2 root root 0 Dec 7 09:45 .Xauthority-l
After some search I saw .Xauthority file is of proper attribute. why do these happen? I also tried these with users other than root, same.
