Package: auto-apt-proxy
Version: 16.8+deb13u1
Severity: normal
X-Debbugs-Cc: timo.weingaertner@quantumsimulations.de

On some hosts I noticed that auto-apt-proxy runs into a timeout and never
yields a proxy even though there is an apt-cacher-ng on the default gateway.
Using htop I saw it recursing into itself through apt-helper.

Adding Acquire::http::Proxy-Auto-Detect= in the hit() function fixes this and
now it yields a working proxy.

Thanks for your bug report.

It already passes `-o Acquire::http::Proxy=DIRECT`. It probably does not
hurt to also pass `-o Acquire::http::Proxy-Auto-Detect=`, but do you
have any idea why this happens only on some hosts? What do these some
hosts have different?

Hi Antonio,

2026-08-12 00:41:02 CEST Antonio Terceiro:

It happened on IPv6-only hosts with static config using networkd, but also on
others. I can look into it in more detail after my vacation, if needed.

But with the recursion removed it was fixed everywhere in my fleet.


Regards
Timo
