Subject: installer freezes when ci.guix.gnu.org cannot be reached

Today I got another chance to try the installer.  I first used the
latest installer image from today (which failed to install Guix because
of a test failure) and then fell back to the 1.3.0 installer image.

Both installers had the same behavior when it came to accessing
ci.guix.gnu.org for substitutes.  I ran the installer on a new build
node, which cannot access ci.guix.gnu.org through the public IP
address.  I forgot to add a line to /etc/hosts to resolve
ci.guix.gnu.org to the local IP.  When I started the installation it
would print two lines and then seemingly freeze.

There was no timeout either.  When the installer is killed and restarted
it fails with other errors that I didn’t record.  I had to reboot and
remember to make the change to /etc/hosts first before starting the
installation.

Hey Ricardo,

I can replicate this issue in a VM, by disconnecting the host network in
the middle of the installation.

I can also replicate it by running a "guix system init
~/guix/gnu/system/examples/desktop.tmpl /tmp" and blocking Berlin IP
while the command is running, this way: "sudo iptables -A INPUT -s
141.80.181.40 -j DROP". The init command hangs forever.

So looks like the freeze issue goes beyond the installer frame and is
more a Guix issue.

In the meantime, we could also extend the installer connectivity check
to make sure that ci.guix.gnu.org is available before proceeding to the
installation.

Thanks,

Mathieu

There's a proposed patch here: 5bc897e0496ff415e653c509ca3b68466e0ed771.

Pushed as ee897e5f51104f41b3c2a0c2cbc7eb4e6c1e4d3e. The core issue
remains, but the installer won't let you install if ci.guix.gnu.org
cannot be reached, preventing the freeze.

I think we can close this one, as the freeze issue is now reported here:
https://issues.guix.gnu.org/52845.

Thanks,

Mathieu
