Deinstalacja Pi-Hole i utrata dostepu do Internetu.

[Matrixx]

Czesc wszystkim.
Zainstalowalem na Debianie Jessie blokera reklam - Pi-Hole, pobawilem sie, nastepnie odinstalowalem, i stracilem kontakt z Internetem. Zmarnowalem kilka godzin szukajac rozwiazania w Googlach, ale nadaremnie.
Aktualnie mam takie konfigi (ustawilem z konsoli):

Siedzialem dlugo w nocy i czesciowo uruchomilem dostep (wchodzi do Internetu i otwiera strony), nie dzialaja niektore skladowe transferu.
Dla przykladu; nie dzialaja przyciski na aliexpress.com albo albo nie moge doprowadzic netinstal do konca
bo w punkcie wskazania zrodlowego mirroru dla instalowanego oprogramowania pojawia sie komunikat na czerwono: "Bad archive mirror" - i tak dla wszystkich mirrorow z listy.
Inny problem jest kiedy wchodze w systemowe Settings a nastepnie Network to pojawia sie komunikat "The system network services are not compatible with this version"
W mojej opini nie jest to problem blokady dostepu do Sieci przez proxy czy iptables, a bardziej nieskonfigurowany Network Manager gnome oraz brak apletu sieci w gornym pasku.
