An old employee at my place of work set up a Ubuntu 18.04 server instance to use the /etc/network/interfaces file for network configuration. This has been causing some issues and I would like to revert back to using the /etc/netplan/*.yaml file approach instead.
I did some research on converting from netplan to interfaces, and it looks like some packages were installed to switch over. However I would like to move back to the original configuration using the .yaml file for my network configuration.
How can I successfully convert back to using netplan? I know how to set the .yaml file up correctly, however it is switching the server back to use this configuration instead of the the /etc/network/interfaces file that I am having trouble with.
Thank you very much. Please let me know if you need any additional information and I will be happy to assist.
