Thank you Luís for taking the time to open this ticket, and respond with the additional logs. I am from the from the kernel team, and I have looked over the dmesg.log that you have provided.
I don't see any networking issues in the kernel log relating to the kernel, but I do see that some Virtual Box modules have been loaded which are out of tree, and unsupported by us. I see that the "VBoxNetFlt" among other Virtual box drivers have been loaded. This one is the Virtual Box "Network Filter Driver". I think there is a good chance that the newer kernel version you are now running is not playing nicely with the VirtualBox drivers. Can you please un- install them, and see if the problem still exists? I do not see any other networking related problems in the kernel log. ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Philip Cox (philcox) ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2080489 Title: Network Manager stops functioning on Ubuntu 24.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2080489/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
