Hopefully netplan sucks less by then? Seriously, current versions are barely usable, and I don’t think I’m doing anything particularly hard. Want to verify your config before committing to it? Nope. Want to delete a vlan? Not happening without bypassing netplan. Want to bring up a vlan on an interface with a long name (which is the default on a fresh Ubuntu install with a NIC in a PCIe slot)? Netplan will accept the…

I was hoping that Canonical has higher standards when it comes to server software, as opposed to something like Snapcraft, but reading this makes me think that maybe they both were developed by the same team.

They were not developed by the same team.

Snapcraft is very much a thing on Ubuntu Server as well. It will "remind" you of that often when interfacing with apt

That sentence in the article almost reads as if it's missing a crucial word ("not"). Did Debian indeed decide to go with Netplan?

The copy/pasta is accurate. Debian is adopting it[1]

Netplan has oversimplified things to cater only to the simplest of topologies. The schema seems unable to capture the richness and modularity of actual networking technologies.

Examples?

Linux allows you to bind a subnet of addresses to an interface so that an application can listen on them. The netplan syntax is poorly thought out and overloads the CIDR notation to specify both the IP and netmask, so it is impossible to specify more than a single address.

I use this functionality in production for high availability configurations and effectively have to have a cron job to use 'ip' directly to fix things up.

What sort of topologies are you attempting?

I was able to set up fiber link aggregation with triple NICs and a custom VLAN and MTU with no issues. It supports bridges and child interfaces just fine.

Can you share your details?

Ubuntu continuing to try to push their snowflakes. nmcli/nmtui works acceptably well. ifupdown-ng works great. What problem is Ubuntu trying to solve?

This, I really don't understand that they want to create a diverging solution for something that already works really well. We don't need 15 different solutions to configure networking.

Imagine looking for a Java solution and the only response you find is in Kotlin... fucking annoying as I have to learn Kotlin to convert it to Java... The same thing with network configuration, you're looking for something that works on Debian and you only find a Ubuntu solution....

If by "only the simplest of topologies" you mean: 4 physical interfaces, bonded with active/backup failover and mii-monitoring, and 20 VLANs, turning off IPv6 on my public interface...

Honestly, I really like netplan, been using it for all my systems for ~5 years now.

It would be more useful for the various major distros to pitch in for easy, simple, congruent CLI, UI, declarative, and API configuration management for common advanced configuration.

Creating artificial lock-in that doesn't work is a double-barrel footgun blast.

The Ubuntu people are like the SystemD people: they just want to reinvent things from scratch and shove it down everyone's throats without any consideration.
