To ensure compatibility with network cards from different manufacturers, I removed the network card configuration from the user data, allowing it to be generated automatically. However, it seems that the final configuration only includes the activated network card. When using other network cards, it doesn't automatically obtain an IP address. This results in a less universally applicable configuration compared to one generated through USB installation. Is this intentional or a bug?

  • Do you just want a generic network config that uses DHCP for all interfaces? You can use late-commands to delete the generated configuration and install a generic config https://askubuntu.com/a/1479946/376778 – Andrew Lowther Sep 19 '23 at 22:17
