@SuperOscar
Kiitos hyvistä ohjeista! Alan tutkailemaan asiaa tarkemmin (sen minkä olympialaisilta ehdin  )

Vähän taustaa.
Minullahan lienee ollut käytössä opensuse jo n. 10 vuotta. Aina olen tehnyt niin, että uusi versio on asennettu ja sen jälkeen olen kopioinut home-hakemiston
ulkoiselta varalevyltä uuden ohjelmiston home-hakemiston "päälle".
Nyt kun jo jonkin aikaa sitten päivitin samalla menetelmällä tw:n kde6:ksi, niin tuli muutama ongelma. niistä ole selvinnyt, mutta nyt tupsahti sellainen ongelma, että internetin oletusohjelmia en saa päivitetyksi.

Asiaan:
Kun päivitän järjestelmäasetuksista oletusohjelmat, niin ne eivät päivity tiedostoihin.
Eli Verkkoselain on firefox, mutta kun avaan thunderbirdistä (=oletussähköpostiohjelmani), niin chromium käynnistyy.
Oletussähköpostiohjelmani on thunderbird, mutta, sähköpostiohjelmana näkyy kmail.

Päivitysyrityksestä tulee tämä herja:

Mitähän tiedostoja kannattaisi tutkailla/pätsäillä?

Virhe toivottavasti kertoo syyn.
Tämä on ensimmäinen kerta, kun yritän luoda virtuaalikonetta puhtaan asennuksen jälkeen.

Taas pelittää, ei huolen häivää.

Toimiiko muilla https://get.opensuse.org/tumbleweed/ ?
Minulla vaan lataa ja lataa.

Eipä toimi...
