Hello, I am getting the following error message. How can I overcome this problem? What exactly do I need to do step by step?

I just installed the operating system. I don't understand what is causing this error.

My Os : Redhat 7.9

SELinux is preventing /usr/sbin/NetworkManager from unlink access on the file /etc/resolv.conf.

***** Plugin restorecon (94.8 confidence) suggests ************************

If you want to fix the label.
/etc/resolv.conf default label should be net_conf_t.
Then you can run restorecon. The access attempt may have been stopped due to insufficient permissions to access a parent directory in which case try to change the following command accordingly.
Do

/sbin/restorecon -v /etc/resolv.conf

***** Plugin catchall_labels (5.21 confidence) suggests *******************

If you want to allow NetworkManager to have unlink access on the resolv.conf file
Then you need to change the label on /etc/resolv.conf
Do

semanage fcontext -a -t FILE_TYPE '/etc/resolv.conf'

where FILE_TYPE is one of the following: NetworkManager_etc_rw_t, NetworkManager_tmp_t, NetworkManager_var_lib_t, NetworkManager_var_run_t, dhcpc_state_t, dhcpc_var_run_t, dnsmasq_var_run_t, hostname_etc_t, named_cache_t, net_conf_t, pppd_var_run_t, systemd_passwd_var_run_t.
Then execute:
restorecon -v '/etc/resolv.conf'

***** Plugin catchall (1.44 confidence) suggests **************************

If you believe that NetworkManager should be allowed unlink access on the resolv.conf file 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:

ausearch -c 'NetworkManager' --raw | audit2allow -M my-NetworkManager

semodule -i my-NetworkManager.pp
