Last evening I made the requested packages upgrade for Ubuntu 18.04.4 Desktop. But now I'm not able to connect to the network anymore with the previous network configuration files. These are the packages upgraded:
NetworkManager.conf file content:
$ sudo nano /etc/NetworkManager/NetworkManager.conf [main] plugins=ifupdown,keyfile [ifupdown] managed=false [device] wifi.scan-rand-mac-address=no
Following these indications: No wired connection - Wired unmanaged ubuntu 18.04
I tried to put
sudo service network-manager restart
followed by a system reboot.
But the problem still persists.
$ sudo nano /etc/netplan/01-network-manager-all.yaml #Let NetworkManager manage all devices on this system network: version: 2 #renderer: networkd ethernets: enp3s0: dhcp4: no addresses: [192.168.1.7/24] gateway4: 192.168.1.1 nameservers: addresses: [18.104.22.168, 22.214.171.124]
network: version: 2 renderer: NetworkManager #renderer: networkd ethernets: enp3s0: dhcp4: trye #dhcp4: no #addresses: [192.168.1.7/24] #gateway4: 192.168.1.1 #nameservers: # addresses: [126.96.36.199,188.8.131.52]
made the wired connection working again.
What happened due to this Ubuntu 18.04 package upgrade?
