Automatická aktualizace se mi nabídla už minulý týden.
Pohledem do repozitářů lze zjistit, že verze 3.0.1 tam byla umístěna 17.července.
Hmm.. vďaka za info, idem zistiť, prečo ju ešte nemám

EDIT: Nemôžem ho nájsť ani po update zdrojov. Pozeral som do repo cez
packages.ubuntu.com a ja tam vidím iba firefox 3.0 nie 3.0.1.

Nepáči sa mi však, že pri apt-get update mi systém vypíše, že niektoré zdroje boli ingnorované, Synaptic však žiadnu chybu nevypisuje:

Načítavajú sa zoznamy balíkov... Hotovo Napríklad:

Aspoň si myslím, že to Ign znamená ignored.
Vďaka za každú odpoveď

EDIT2: Práve dnes som nejaké updaty urobil, takže zdroje pravdepodobne fungujú.
