Tengo un servidor antiguo que ejecuta Ubuntu 18.04.6 LTS y sospecho que alguien intentó instalar o actualizar los paquetes incorrectos de Ubuntu 20.04, lo que resultó en un apt roto y el llamado "Frankensystem".
Me gustaría solucionar este problema sin tener que reinstalar todo el sistema, especialmente porque el servidor está ubicado en una ubicación remota. ¿Es posible reparar los paquetes rotos uno por uno y, de ser así, cómo puedo hacerlo?
Estos son los errores que encuentro:
Al correr sudo apt update:

cuando revisé /usr/lib/x86_64-linux-gnuencontré libapt-pkg.so.5.0que existe y pero nolibapt-pkg.so.6.0
Además, /usr/lib/python3/dist-packagesencontré apt_pkg.cpython-38-x86_64-linux-gnu.solo cual es extraño, porque la versión de Python3 es 3.6.9.
Respecto a las copias de seguridad, encontré estos archivos.

¿O puedo usar cualquiera de estos archivos para restaurar el sistema a un estado funcional?
