Network unreachable in Geary.Devel flatpak

[fedelibre (Federico Bruni)]

Since a few days I cannot use anymore Geary.Devel flatpak from gnome-nightly.

Looking at the logs the main suspect might be ipv6:

I tried disabling ipv6 in GNOME Settings, but the Apply button is not activated:

[fedelibre (Federico Bruni)]

If I manually disable ipv6:

sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1

Connection error seems to go away.
But messages cannot be loaded.

I cannot reproduce the problem anymore:

Famous last words… now I’m reproducing 100% of times using either Geary or Geary.Devel flatpaks.

I guess the key error is:

GLib-GIO:GSocketClient: Address enumeration failed: (null)

I tried disabling ipv6 in GNOME Settings, but the Apply button is not activated:

This is a known bug and fix is coming:
https://bugzilla.redhat.com/show_bug.cgi?id=1932674

While waiting for it, it seems that changing the DNS server using nmcli fixes the network problem:

nmcli con mod 'NETWORK NAME' ipv4.dns "8.8.8.8 1.1.1.1"
nmcli con down 'NETWORK NAME'
nmcli con up 'NETWORK NAME'

[fedelibre (Federico Bruni)]

No, adding other DNS servers did not solve the issue.
I’m having this problem again after a system&flatpak upgrade + reboot.

Glib bug?

Currently nightly is working fine for me, but if GLib’s sockets aren’t able to look up addresses when connecting, then that would indicate either a GLib bug or a system configuration issue.

Maybe try doing a flatpak update and see if that helps, if not file a GLib bug?

Let us know how it goes.

[mjog (Michael Gratton)]

A good test is usually to try some other GLlib networking based apps - Web nightly would be a good example.

[fedelibre (Federico Bruni)]

It’s not GLib, it’s a systemd issue.
Eventually I found the Fedora bug.

It seems solved with this version of systemd:

$ rpm -q systemd
systemd-248~rc2-3.fc34.x86_64
