Quiero actualizar mi LTS 18.04.6 al siguiente LTS, pero no me deja porque cree que hay actualizaciones que debo hacer primero. Sin embargo, estas actualizaciones no funcionan y generan un error con "verifique su conexión a Internet", creo que porque ahora solo están disponibles como soporte extendido.
Intenté cambiar /etc/apt/sources.list para usar old-releases.ubuntu.com, pero no parece ayudar.

Bien, supongo que me equivoqué al cambiar mi /etc/apt/source.list a old-releases.ubuntu.com y no ayudó, pero desmarcar los 4 o 5 inferiores en la GUI de repente desbloqueó la actualización. .
Uno se pregunta si simplemente desmarcar todas las fuentes desde el principio hubiera funcionado también, pero lamentablemente ya no puedo probar esto.
La actualización parece haber ido bien.
