Dear Maintainer,
With the above version of apt-cacher-ng we encounter a bug while installing
packages. (In our scenario the apt-cacher-ng itself runs in a Docker image
based on ubuntu:jammy-20230126 (22.04 LTS)).
The below error message happens for many packages (below is a more complete
log):
E: Failed to fetch
http://archive.ubuntu.com/ubuntu/pool/main/a/automake-1.16/automake_1.16.1-4
ubuntu6_all.deb 503 Connection closed, check DlMaxRetries [IP: x.x.x.x
3142]
This occurs reproducibly in scenarios where many packages will be installed
at a time (in our case while building docker images). This behaviour is not
100% reproducible and might not occur if only a low number of packages is
being installed. It also sometimes works without issues for a large number
of packages. But most of the times starts failing after 40-60 packages.
The only reliable workaround we found was "downgrading" the apt-cacher-ng
version to 3.6.4 (based on Debian 11, docker image
debian:bullseye-20230208). There is also an open bug report on the ubuntu
bug tracker:
https://bugs.launchpad.net/ubuntu/+source/apt-cacher-ng/+bug/1960264 but it
does not only occur with PPAs, but also regular repositories.
Below is the more detailed log for a situation with a low amount of packages
being installed.
