Proč jsou načítání aktualizací Apt-get tak velké?

Tato otázka zde již obsahuje odpovědi :Uzavřeno před 8 lety.

Možný duplikát:
velikost seznamů aktualizací apt-get je příliš velká

Po vyčištění instalaci 12.04 (Release Candidate) a přijetí všech aktualizací a upgradů do dnešního dne, zjistil jsem, že sudo apt-get update vždy načítá informace v rozsahu MB, asi 12 MB, zatímco sudo apt-get upgrade většinou nemá co stahovat.

Největší tři načtení, které vidím, jsou:

http://archive.ubuntu.com precise/universe Sources [5,019 kB]
http://archive.ubuntu.com precise/main i386 Packages [1,274 KB]
http://archive.ubuntu.com precise/universe i386 Packages [4,796 KB]

Jsem si docela jistý, že sudo apt-get update načtení nebyly nikde tak velké s 11.10 a zřídka překročily dokonce 1 MB.

Moje otázka zní:Jsou tyto velké načtení jen proto, že 12.04 je nedávné, nebo budou tyto velké aktualizace normou?

(fast na prvním řádku je to, že používám apt-fast místo apt-get )

Přijatá odpověď:

Zakázal jsem deb-src apt.conf řádků na odpověď mikewhatever. Tím se to snížilo, stejně jako u vás, na ~6 MB.

Pak jsem si všiml, že když apt získával informace o balíčku, procházel přes 192.168.1.3 – můj squid-deb-proxy server (který běží 11.10; ještě jsem se nedostal k jeho aktualizaci). Odinstalování squid-deb-proxy-client z klienta vrátil velikost stahování informací zpět do normálu.

EDIT:Aaa vrátilo se to ke svému starému chování. Také jsem zkontroloval virtuální počítač na svém Macu (čerstvá instalace stabilního vydání v den, kdy vyšlo), který čas od času spouštím; Informace o aktualizaci balíčku jsou také velkým stahováním. Nechám tuto odpověď jednoduše, abych zdokumentoval, že toto řešení nefunguje. Kromě toho jsem zasekl.
