Fixed! But with a litle different way, we reduce the problem only on the dns that doesnt pick unfortunantelly after reboot again i had the same entries, so i searched a litle and i found a different way to set permament dns
I run
nmcli con show --active
To see active interfaces,
i see my eth0 with id ,etc and i set with that command the dns
nmcli con mod "501ba88f-a6be-4d68-bfd6-84696ba74aab" ipv4.dns "8.8.8.8, 8.8.4.4"
after reboot everything works (ping)
i recheck the file resolv.conf and i have this:
# /etc/resolv.conf and seeing this text, you have followed the symlink.
#
# This is a dynamic resolv.conf file for connecting local clients to the
# internal DNS stub resolver of systemd-resolved. This file lists all
# configured search domains.
#
# Run "resolvectl status" to see details about the uplink DNS servers
# currently in use.
#
# Third party programs should typically not access this file directly, but only
# through the symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a
# different way, replace this symlink by a static file or a different symlink.
#
# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.
