Public bug reported:
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.
Thanks for your assistance.
