El sistema de paquetes está roto. No se puede solucionar

Probé varias cosas en línea para solucionar este problema, como ejecutar sudo apt-get -f installysudo apt-get clean

esto es lo que obtengo cuando intento actualizar con el actualizador de software:

Check if you are using third party repositories. If so disable them, since they are a common source of problems.
Furthermore run the following command in a Terminal: apt-get install -f

Intenté seguir la respuesta de esta guía. pero no ayudó:¿Cómo resuelvo dependencias no satisfechas después de agregar un PPA?

resultado de sudo apt-get update:

E: The repository 'http://ppa.launchpad.net/nathan-renniewaldock/flux/ubuntu focal Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Estoy ejecutando la versión 20.04 por cierto. Soy un novato, así que no estoy seguro de lo que estoy haciendo, solo necesito arreglar esto.

No puedo instalar Synaptic Package Manager porque no puedo instalar ningún programa

Respuesta1

El paso 1 es eliminar el repositorio roto de su lista de fuentes. No está disponible para 20.04 Focal.

Puede hacerlo abriendo la herramienta Software y actualizaciones, haciendo clic en la pestaña Otro software y luego desmarcando la casilla junto al repositorio, o escribiendo sudo add-apt-repository -r ppa:nathan-renniewaldock/fluxen una terminal.

Si hiciste el último procedimiento, haz un sudo apt update.

Bien, todavía hay problemas después de eso.

Paso 2 revisado

Mirando la salida de apt policy libpam-modules---

Hay una versión huérfana del paquete 1.3.1-5ubuntu4.2instalada. No provino de los repositorios normales. Parece que agregó un ppa, instaló el paquete y luego eliminó el ppa. O lo instaló de alguna otra forma no estándar.

Intentaría usar Synaptic Package Manager para forzar la instalación 1.3.1-5ubuntu4.3. Si te permite en un sistema roto. PeroExamine cuidadosamente los cambios sugeridos antes de aceptarlos.
