换DNS(很重要) sudo vim /etc/resolv.conf ————————————————
This is /run/systemd/resolve/stub-resolv.conf managed by man:systemd-resolved(8).
Do not edit.
#
This file might be symlinked as /etc/resolv.conf. If you’re looking at
/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.
