Amikor kijött a Ubuntu 26.04 gondoltam felteszem a virtualboxba. Letöltöttem a deb fájt és a Gbebivel elkezdtem felrakni. A telepítés eljutott oda, hogy configurálni akarta a secure boot-ot. Nem értettem minek gondoltam el napolom a kérdést és ha nehezen is de kiléptem belőle. Napokig nem használtam mert a laptoppal dolgoztam amire végül is Ubuntu 26.04 GNOME-t tettem fel. Majd vissza jöttem ide és próbáltam frissíteni de nem ment. A frissítés kezelő a gép indítása után a virtual box konfigurációs ablakát dobja be, vagy ha ezt bezárom záros határidőn belül nem történik semmi. Próbáltam parancssorból, ezt a választ kaptam:

Ezek nekem nem segítettek. Volt még egy eshetőség a frissítés kezelő idönként beadla a javítást de az fe oldotta meg a problémát.
Hogyan javithatom a hibát.
Köszönöm.
