Solucione el error "Encontró una sección sin paquete:encabezado" en Ubuntu

Hoy, me encontré con el siguiente error cuando intento actualizar mi sistema de escritorio Ubuntu 20.04 LTS.

$ sudo apt upgrade

Salida de muestra:

Reading package lists... Error!
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/ny-mirrors.evowise.com_ubuntu_dists_focal_universe_binary-i386_Packages
E: The package lists or status file could not be parsed or opened.

Lo intenté de nuevo con el administrador de paquetes Graphical Synaptic. ¡Pero sin suerte! ¡Recibí el mismo error!

Este es uno de los problemas comunes en los sistemas basados ​​en Ubuntu y Debian.

Después de leer el resultado con un poco de atención, entendí que las listas de paquetes o el archivo de estado están dañados por algún motivo, por lo que no se pudieron analizar.

Para aquellos que se preguntan, el archivo de estado contiene información sobre los paquetes deb instalados. Podemos resolver este problema eliminando la lista de paquetes dañados y el archivo de estado y regenerarlos como se describe a continuación.

Corregir el error "Encontrado una sección sin paquete:encabezado" en Ubuntu

Paso 1. Primero, elimine la lista de paquetes dañados usando el comando:

$ sudo rm /var/lib/apt/lists/* -vf

El comando anterior eliminará toda la lista de fuentes del paquete de su sistema Ubuntu.

Aquí está el resultado de muestra de mi escritorio Ubuntu 20.04 LTS:

Paso 2. Ahora, ejecute el siguiente comando para reconstruir la lista de fuentes del paquete:

$ sudo apt upgrade

Esto tomará un tiempo dependiendo de su velocidad de Internet. ¡Se paciente!

Paso 3. Una vez que se regenere la lista de paquetes, realice una actualización completa ejecutando los siguientes comandos uno por uno:

$ sudo apt upgrade

$ sudo apt upgrade

$ sudo apt dist-upgrade

Paso 4. Después de actualizar el sistema Ubuntu, borre el caché del paquete:

$ sudo apt autoclean

$ sudo apt autoremove

Paso 5. Finalmente, cierre todos los programas abiertos y reinicie su sistema:

$ sudo reboot

El problema ya debería haber desaparecido.

Paso 6: Por si acaso, si aún ve el mismo error, elimine el archivo de estado y vuelva a generarlo con los siguientes comandos:

$ sudo rm /var/lib/dpkg/status

$ sudo touch /var/lib/dpkg/status

$ sudo apt upgrade

No olvide realizar una actualización completa del sistema y limpiar el caché de apt y luego reiniciar su sistema.
