Не устанавливаются DNS
У меня Xubuntu 22.04, в какой-то момент слетели DNS. Использую vless ВПН с клиентом nekoray - возможно его работа. Сайты не открываются ping выдает Temporary failure in name resolution. Телеграм кстати работает. Точно не проблема с роутером потомучто на другом компьютере у меня точно такая же ОС с таким же ВПН (даже конфиг тотже) и там все работает окей.

То есть нет днсов ни для одного устройства, в т.ч. для wifi… Вот другие выводы:
$ cat /etc/resolv.conf
nameserver 127.0.0.53
options edns0 trust-ad
search .
$ cat /etc/systemd/resolved.conf
[Resolve]
#DNS=
$ cat /etc/NetworkManager/NetworkManager.conf
[main]
plugins=ifupdown,keyfile
[ifupdown]
managed=false
[device]
wifi.scan-rand-mac-address=no
Проверил работу нетворк менеджера и systemd-resolved

То есть если я правильно понимаю он должен был выдать лог по девайсу wifi но его нет…

Здесь таже самая пробелма как я понял…
Еще попробовал явную установку dns для роутера nmcli connection modify "TP-Link_C4A2" ipv4.dns "77.88.8.8 77.88.8.1" - работает чере раз и с очень большим пингом до 10сек.
