photon os 4.0 loses static ip after update 5-10 .61-5 .ph4-esx to 5.10.78-4.ph4-esx

[IgnacioProcisa]

Hello, today I have updated photon 0s 4 from version 5-10 .61-5 .ph4-esx, having three security notifications.

My MVs have two network adapters, eth0 with static ip and eth1 with dynamic ip. Running smoothly. Prep Post Operational & securityinfo Post update Networkctl status Static IP configured and not modify

After installing the updates, the eth0 adapter does not have the ip that is configured manually, doing an ip or an ifconfig the adapter appears without IP. If we do a networkctl, it tells me that the adapter is degraded and configuring. Checking in other VMs without updating the status is routable and configured.

I can only get ip again using a DHCP for the eth0 adapter.

What has happened?

Can you attach Networkd logs from journal ? It seems these IP is dropped by kernel. Does restart Networkd restores your ip ?

Same issue here at a freshly installed Photon OS with ISO "photon-4.0-ca7c9e933.iso". After updating with tdnf update and a reboot, eth0 didn't use the configured Static IP. A restart of systemd-networkd didn't solve the problem. I've managed to solve the issue with deleting the file /etc/systemd/network/99-dhcp-en.network

Here are some screenshot while it was not working:

networkd log from journal

networkctl status 2

/etc/systemd/network/99-static-en.network

Thanks for the data. If you see eth0 configured on 99-dhcp-en.network networkctl status 2

you need to rename 99-static-en.network file to 10-static-en.network` like that. Note that all configuration files are collectively sorted and processed in lexical order.

i have had the same issue on CBL Mariner.

the error was that the config file needs to be readable by group systemd-network

Same issue on a fresh install of 4.0 Rev2 from ISO (photon-minimal-4.0-c001795b8): after tdnf upgrade/tdnf distro-sync, /etc/systemd/network/99-dhcp-en.network is added alongside the existing /etc/systemd/network/99-static-en.network (which contains the manual IP configuration set up during installation), overriding the static configuration which breaks networking on a DHCP-less network.

Please use a higher priority for the installer-generated static network file, so it doesn't get overridden by the 99-dhcp catch-all.

thank you, this fixed my issue after doing an update.

root@...[ ~ ]# tdnf -y install systemd (updated to systemd.x86_64.247.13-2.ph4) (a library update should not cause a network disconnect)

Hi @joel72265 , I think renaming 99-static-en.network file to 10-static-en.network itself should solve your issue. Could you share from which version of systemd you upgraded it to 247.13-2?
