# matchpathcon /etc/resolv.conf /etc/resolv.conf system_u:object_r:net_conf_t:s0 Which means the resolve.conf is mislabeled. If you execute # restorecon -Rv /etc/resolve.conf are you able to reproduce it? If so, please reopen the bug. Thank you. BTW The alert told you how do fix. Any idea how you got this mislabeled? |
