With all 20190409 updates (including the same systemd version as before, 242~rc3-1.fc31), my network works again. Yesterday, I had to downgrade systemd to get the network back, (which I'm guessing is related to this bug). See [bug 1697667] for selinux-policy, likely relevant here. Yes, this seems to be the same or very similar to 1697667. Please check if the update for 1697667 also fixed your issue.
> 2 warning: %triggerin(systemd-udev-242~rc3-1.fc31.x86_64) scriptlet failed, exit status 1
This scriptlet just calls udevadm control --reload, so the report you get is most likely caused
by udevd not running. There's also a bug open about this: #1698391.
I just pushed a change to systemd.spec to silence those errors.
*** Bug 1697290 has been marked as a duplicate of this bug. *** I think this should be fixed now. If the problem still occurs, please reopen. |
This is more a heads-up for now since I didn't get to investigate this properly, but have suffered a bit of a pain earlier today after update of systemd: # dnf history info -4 | grep systemd Upgrade systemd-242~rc3-1.fc31.x86_64 @rawhide Upgraded systemd-241-4.gitcbf14c9.fc31.x86_64 @@System Upgrade systemd-container-242~rc3-1.fc31.x86_64 @rawhide Upgraded systemd-container-241-4.gitcbf14c9.fc31.x86_64 @@System Upgrade systemd-devel-242~rc3-1.fc31.x86_64 @rawhide Upgraded systemd-devel-241-4.gitcbf14c9.fc31.x86_64 @@System Upgrade systemd-libs-242~rc3-1.fc31.x86_64 @rawhide Upgraded systemd-libs-241-4.gitcbf14c9.fc31.x86_64 @@System Upgrade systemd-pam-242~rc3-1.fc31.x86_64 @rawhide Upgraded systemd-pam-241-4.gitcbf14c9.fc31.x86_64 @@System Upgrade systemd-rpm-macros-242~rc3-1.fc31.noarch @rawhide Upgraded systemd-rpm-macros-241-4.gitcbf14c9.fc31.noarch @@System Upgrade systemd-udev-242~rc3-1.fc31.x86_64 @rawhide Upgraded systemd-udev-241-4.gitcbf14c9.fc31.x86_64 @@System 2 warning: %triggerin(systemd-udev-242~rc3-1.fc31.x86_64) scriptlet failed, exit status 1 # journalctl -b-7 --no-hostname -g udev Apr 08 13:08:39 systemd[1]: Listening on udev Control Socket.

[...] So the main problem here may be that selinux-policy (3.14.4-8.fc31.noarch) lacks some mitigation for: > AVC avc: denied { mounton } for pid=850 comm="(md-udevd)" path="/run/systemd/unit-root/proc/sys/kernel/domainname" dev="proc" ino=19582 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:sysct> ? All in all, downgrading back to systemd-241-4.gitcbf14c9.fc31.x86_64 fixed the problem for me.
