I just lost 3 days to this issue before I realized what was happening. I realize this is an edge case, and understand the issues with fixing this, but at least some type of better error messages would have helped prevent that waste of time.
I was trying to setup a host to run docker with macvlan networks mapped to vlan interfaces on a pair of USB ethernet adapters connected to a BRIX used for testing. Couldn't get a bond on the pair to work, couldn't figure out why, then tried for just VLAN interfaces, and that didn't work either. Thought I was losing it, didn't seem that hard. Not sure how I figured it out, but realized if I switched back to using eth1, eth2 for the USB ethernet devices, using "net.ifnames=0 biosdevname=0" boot options + old-style mac-address rules to map, I could get everything to work. But, wasn't happy with the workaround, as I'd prefer to use the new predictable names. I like the idea of using last 6 digits of Mac address. I thought of doing this: sudo ln -s /dev/null /etc/udev/rules.d/73-usb-net-by-mac.rules to go back to slot names, but if I plug into different ports, names change, so no. Perhaps some different prefix other than enx to avoid confusion, usb123456 anyone? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1567744 Title: USB NICs get too long name for ifupdown aliases or bridge names Status in systemd package in Ubuntu: Triaged Bug description: I have a USB NIC that is connected to my denial system.
