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 Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1761911 Title: Have to manually "sudo ifconfig eth0 up" and "sudo dhclient eth0" after every reboot Status in network-manager package in Ubuntu: New Bug description: I did an upgrade with "sudo apt-get dist-upgrade", and it removed network-manager and network-manager-gnome. I could not connect to my LAN afer that. I was able to find instructions for downgrading the libnl packages at https://askubuntu.com/questions/727127/last-upgrade-crashes-network-manager-no-internet-connection-no-applet I am able to get online again by running the following commands sudo ifconfig eth0 up sudo dhclient eth0 (Fortunately, I have a Ethernet I can plug in to.) I have to do this every time I reboot. This is inconvenient as a usually use Desktop Sharing with another computer as the client. I use an SSH tunnel for security. This means that every time I reboot, I have to physically access the computer's console to enter the ifconfig and dhclient commands to get the computer back on the network. I tried to reinstall network-manager and network-manager-gnome, but the command results said there were dependencies that prevented the installation. The fixes in the web page referenced above do not help, so I'm reporting this as a bug.
