Bug#1016897: Temporary failure resolving 'deb.debian.org'

[probal basak]

Package: apt

Version: apt 2.2.4 (amd64)

We have GitHub actions setup for building/running some scripts.

However, we see some issues while the script is run.

Please note that with nslookup, deb.debian.org is getting resolved as expected.

Please find the error snippet below:

+ update
+ apt update
WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
Ign:1 http://deb.debian.org/debian unstable InRelease
Ign:1 http://deb.debian.org/debian unstable InRelease

All packages are up to date.
W: Failed to fetch http://deb.debian.org/debian/dists/unstable/InRelease  Temporary failure resolving 'deb.debian.org'
W: Some index files failed to download. They have been ignored, or old ones used instead.

Can you please look into the issue and suggest any way to avoid the issue?

Note that APT does a whole bunch of SRV record look ups, and implements
happy eyeballs 2.

Can *you* please do that? You're the one who can reproduce that. Patches welcome.

We don't use GitHub or actions, but a simple search on GitHub
https://github.com/search?q=http%3A%2F%2Fdeb.debian.org+path%3A.github
finds more than a hundred matches.

This is not a recommendation for any of these projects/setups:
Some of the matches look dangerous if not used with extreme caution
even on the very short glance I gave the first page. And no, I don't
have a best-practice/recommendation for it as I am not using it.


The important part is that I doubt all these have broken CI lying around,
so its something about YOUR setup/action/project/… that you haven't told
us and you will have to figure out as we don't know your project.


So first come up with a reliable way to reproduce your problem by
stripping down your project to the bare minimum needed and share this
reproducer here with us.
