Funcionó bien con Ubuntu 18.04 pero en Ubuntu 20.04 el problema con apt-cacher-ng es el siguiente:

Y también el problema es solo con 20.04, ya que no lo encuentro con 18.04 (estaba bien para máquinas reales y VM de la misma manera). Y el problema es solo con sudo apt update, si actualizo el repositorio directamente y luego usoapt-chacher-ngcomoapoderadopara descargar los paquetes, no hay problemas. Entonces, ¿dónde exactamente va mal?
Respuesta1
apt updateTambién veo este error en 20.04 a través de apt-cacher-ng, aunque apt upgradeparece que todavía funciona. Noté que los archivos en el servidor tenían .xzextensiones, si eso es una pista.

No he podido identificar una solución todavía... Intenté agregar esto acng.cnf(para marcarlo como "volátil") pero no estoy seguro de si solucionó el problema, ya que el problema desapareció en el cliente después de comentar apt. proxy y realizó unaapt update
