[Ubuntu 16.04 LTS] Błędy podczas aktualizacji poleceniem apt update

Od pewnego czasu przy aktualizacji poleceniem

sudo apt update

otrzymuję co raz więcej błędów. Aktualnie wygląda to tak:

Jak to naprawić? :unamused:

Ale wiesz, że wszystko masz podane w tym co wkleiłeś? Usuń zduplikowane wpisy dotyczące repozytoriów.

OK ale jak to zrobić? W linuksach jestem początkujący. No i o co chodzi z tymi wpisami “Stary:1” itd.
W wynikach poleceń niżej widzę że niektóre repo nie są już wspierane, muszę je zmienić na inne albo usunąć?

Z tego, co zauważyłem, to w podanych przez Ciebie plikach jeden wierz - jeden wpis. Wiersze zaczynające się od hasha (’#’) to komentarze, więc nie musisz ich usuwać. Usuwasz powielające się linijki. W konsoli wykonaj sudo su, wprowadź swoje hasło, a potem nano <pełna ścieżka do pliku>. Zapisujesz chyba przez CTRL+W, ale na dole nano podaje skróty klawiszowe. Jeżeli nie dasz rady, to zainstaluj Synaptic i w nim odszukaj opcję zarządzania repozytoriami lub podobną i usuń z jego poziomu powtarzające się wpisy.

Z sources list usuń wpisy dotyczące opery ponieważ powielają się z repozytorium.
Nie używaj ppa, chyba że jest to niezbędne, a widzę że pododawałeś ich sporo.
