Recently, I did an upgrade to F39 via dnf system-upgrade. For the first

I get a message saying "limited network connectivity", which means, my
wired network is up but can't reach the outside world.
The journals tell me that the name resolution is not working (see
attached log). I didn't find out why it failed, but restarting
systemd-resolved usually cures the problem. The problem that the service
fails on startup still remains, but not on every boot. Sometimes, say in
10 % of bootings, the problem doesn't occur.
If those things matter:
- Desktop computer with KDE-Plasma (X11)
- kernel 6.6.8-200.fc39.x86_64
- NIC: Intel 82574L with kernel driver e1000e
I have the faint idea thast there might be a race condition between
services on startup,
Any pointers to debug that further would be welcome.

That is very odd. | have seen a number of people seeing odd things failing
as a result of selinux labelling errors. You could try to the auto relabelling and
see if that fixes it.
touch /.autorelabel
reboot
Other then that you could try running /usr/lib/systemd/systemd-resolved as root
in debug mode and see if reports any errors.
systemctl stop systemd-resolved
SYSTEMD_LOG_LEVEL=debug /lib/systemd/systemd-resolved
Thanks, Barry, you were right in suspecting selinux: After
autorelabelling, I booted the system for several times without the
problem ever reoccurring. So for me, there is sufficient statistical
evidence that my problem is solved. But an issue remains: Why got my
system mal-labelled? I didn't do many things to it after the upgrade,
and shouldn't be labelling be part of the system-upgrade process?
But thanks again for your help.
