Resúmen:

SELinux is preventing access to files with the label, file_t.

Descripción Detallada:

SELinux permission checks on files labeled file_t are being denied. file_t is
the context the SELinux kernel gives to files that do not have a label. This
indicates a serious labeling problem. No files on an SELinux box should ever be
labeled file_t. If you have just added a disk drive to the system you can
relabel it using the restorecon command. For example if you saved the home
directory from a previous installation that did not use SELinux, 'restorecon -R
-v /home' will fix the labels. Otherwise you should relabel the entire file
system.

Permitiendo Acceso:

You can execute the following command as root to relabel your computer system:
"touch /.autorelabel; reboot"
