UBUNTU - copy connection profiles to another computer

As mentioned by others, Wi-Fi connection files in system-connections directory have the interface MAC address included. This need to match your current setup hence the procedure is:

copy all files from old machine to new machine from/to directory:

/etc/NetworkManager/system-connections

sudo cp -Ri /etc/NetworkManager/system-connections /media/bruno/Elements/bruno-ubuntuPC/system-connections/ 

Now on the new PC:

change MAC address entry in each file from old MAC to new MAC. As root:

cd /etc/NetworkManager/system-connections

sudo sed -i -e 's///' *


Just in case, restart network manager:systemctl restart NetworkManager


service network-manager restart








In the end:




change permissions:


sudo chmod 0600 *
sudo chown root:root *
