Before I submitted this, I had run the following command, per the web page mentioned above.
sudo apt-get install libnl-3-200=3.2.21-1 libnl-route-3-200=3.2.21-1 libnl-genl-3-200=3.2.21-1 After submitting this, I ran the following commands: sudo apt-get update sudo apt-get install network-manager network-manager was reinstalled, and my server gets connected to the LAN again automatically after I reboot. network-manager-gnome was also reinstalled. I'd like to know if I can safely do sudo apt-mark unhold libnl-3-200 libnl-genl-3-200 libnl-route-3-200 For now, I'll just stick with the downgraded libnl packages as I don't want to have more networking problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1761911 Title: Have to manually "sudo ifconfig eth0 up" and "sudo dhclient eth0" after every reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1761911/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
