:SELinux is preventing /usr/bin/chcon from 'read' accesses on the None sessions.
:
:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that chcon should be allowed read access on the sessions <Unknown> by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:Do
:allow this access for now by executing:
:# grep chcon /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

if fixed in the latest policy. Please update your system.


avc:  denied  { mac_admin } for  pid=1781 comm="chcon" capability=33 

It means you were trying to set that the kernel/policy does not know about.
