Ubuntu rename Wi-Fi to "eth0"

  • 772

I need to install a software (iCEcube2 from Lattice Semiconductor) on a Ubuntu 20.04 machine. Apparently there is something hardcoded in this software related to license checking that requires the computer to be connected to the internet via a connection with name "eth0" (link). I have tried creating the file /etc/udev/rules.d/70-persistent-net.rules with the following content

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="XX:XX:XX:XX:XX:XX", ATTR{dev_id}=="0x0", ATTR{type}=="1", NAME="eth0"

where XX:XX:XX:XX:XX:XX is actually my MAC address. After this I restarted the computer. It does not work. I also tried the method described in the link before under the title License checkout failed: hostid of this system does not match the hostid.

The option 1. in this SO answer, i.e. sudo ip link set wlp2s0 name eth0 works, however it is temporal.

  1. On the TinyFPGA forum it is suggested to use 2 lines, not 1:

    Going through the interface issue

    Lattice iCEcube2 license takes into account the MAC address of the computer. In order to work, the interface must be labeled as eth0.

    sudo ip link add eth0 type dummy
sudo ip link set eth0 address {mac}

    where ip link show can be used to show what {mac} needs to be what is shown at the name it is shown now for your NIC.

    however it is temporal.

    If they are temporary your settings are likely rewritten by networkmanager, a dhcp server, dhclient, and/or another tool. You would need to disable that

    or

    you could add those 2 lines to /etc/crontab.
