/usr/bin/udevadm: symbol lookup error: /usr/bin/udevadm: undefined symbol: ifname_valid, version SD_SHARED

This looks like a problem with udevadm compilation/linking. Reassigning.

udevadm compilation/linking is fine. ifname_valid is a symbol from an internal library that's been renamed recently and *new* udevadm uses the new name. The problem here is that there is a mix of new /usr/lib/systemd/libsystemd-shared-239.so (systemd-libs rpm) and old /usr/bin/udevadm (systemd-udev rpm) on the system at the point NetworkManager's post scriptlet is run. That's because NetworkManager doesn't have Requires(post): systemd-udev.

Steps to reproduce:
1. Take an older installation of CS8 (with systemd < 239-51).
2. Run "yum update NetworkManager systemd".
3. Observe that systemd-libs is updated before NetworkManager, but systemd-udev after it.

Comment 11 Vladimir Benes 2021-11-11 11:42:14 UTC

Requires(post): systemd-udev added to spec file
