Network Manager tools (nmtui nmcli) fail to update the IP address on v9.5 This worked 100% on 9.4, however after upgrade to 9.5 this fails with an error message. If I manually edit the interface config file for Network Manager, restart the service from the console and then ifdown/ifup the interfac…

I have found the problem - When Rocky9.4 is upgraded to Rocky9.5, the latest version of NetworkManager is not installed. I had to manually upgrade NetworkManager and NetworkManager-tui to the latest version, and then it started working as expected after the Service was restarted.

Hi, I am so sorry… The nmtui error message on trying to change the IP Address under the interface Edit screen: Error Message: Unable to save connection: 802-3-ethernet.mac-address-denylist: unknown property nmcli: nmcli c modify ens33 ipv4.address 10.255.1.46 Error: Failed to modify connection…

Fascinating. The man nm-settings does list that property for me: 802-3-ethernet.mac-address Alias: mac If specified, this connection will only apply to the Ethernet device whose permanent MAC address matches. This property does not change the MAC address of the device (i.e. MAC spoofing). Forma…

I was adding/removing/changing the mac-address. It was only the ip-address that was being changed. In fact, I have never used the mac blacklist or the mac denylist. No entry was added to them. This always worked with no issues in Rocky 9.4 and before. Only since Rocky 9.5 was installed has this pro…

[image] conradc: It was only the ip-address that was being changed. However, that operation is most likely something like: Read saved config Modify config Store config And it seemingly does now: Read garbage Refuse In other words, there is never “only X to change” – the whole config has…

[image] jlehtone: ethernet.mac-address-blacklist There is not any array in the config named as either mac-black-list or mac-deny-list. There is no entry to edit and nothing was added. Even the nmtui config editor tool does NOT list these entries. Why not try it on your own system and see.|

How about trying that with the nmtui tool. I only tried to use the nmcli because of an error shown in the nmtui tool

That is how it used to work under Rocky9.4 - I only get the error now with Rocky9.5 (Upgraded from Rocky 9.4). Trying to make sure the blacklist is empty, then gives an error that the mac-denylist variable does not exist. typing: nmcli c show ens33 | grep list, only shows the mac-blocklist variab…

My config file is: cat /etc/NetworkManager/system-connections/ens33.nmconnection [connection] id=ens33 uuid=6ec6c696-04f9-30c2-ae18-5a7190807575 type=ethernet autoconnect-priority=-999 interface-name=ens33 timestamp=1739862592 [ethernet] [ipv4] address1=10.255.1.44/24,10.255.1.250 dns=41…

Rocky 9.5 Network Manager tools (nmtui nmcli) fail to update the IP address

I don’t think that we can explain the message before we see it.

Is that nmcli con down $conn-name and nmcli con up $conn-name or some legacy scripts?

Which files, exactly?
