Thank you for your bug report, could you do $ apport-collect 1975549
on the machine at the time you are having the issue? ** Changed in: network-manager (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1975549 Title: NetworkManager uses tethered Android phone as ethernet connection instead of wired ethernet connection Status in network-manager package in Ubuntu: Incomplete Bug description: I'm running Kubuntu 22.04 LTS, x86_64, fully patched. I've been having trouble the last week or two ssh'sing into the machine, and printing from the machine when I am sitting at the keyboard. I also could not connect to my external firewall when sitting at the keyboard. I keep a Google Pixel 4a tethered to the USB hub for charging. The Android phone is running Android 12, and the phone is set to "USB Tethering". The phone is fully patched, too. I found if I reboot the machine with the phone tethered, then the machine uses the Android phone as the ethernet connection. It literally calls the connection "ethernet", as if it was using the network adapter. This is new behavior over the last week or two. This is unexpected behavior for three reasons. First, it is new behavior. Second, the wired gigabit ethernet connection is not used by default. And thrid, the Android phone's connection is called "ethernet" instead of something more meaningful like "USB" or "Android" or "wired hotspot". The third item ("ethernet" name when using Android phone) was misleading enough to waste a lot of time troubleshooting the issue. I thought I had an odd firewall issue or a mDNS issue. The reason I was having so many troubles, like printing and ssh, is the Android phone uses Wifi and it is on a different VLAN and subnet to keep traffic segregated from my trusted internal network. ----- It looks like I am running network-manager via systemd: # service systemd-networkd status ● systemd-networkd.service - Network Service Loaded: loaded (/lib/systemd/system/systemd-networkd.service; disabled; vendor prese> Active: inactive (dead) Docs: man:systemd-networkd.service(8) # service network-manager status ● NetworkManager.service - Network Manager Loaded: loaded (/lib/systemd/system/NetworkManager.service; enabled; vendor preset: > Active: active (running) since Mon 2022-05-23 21:16:52 EDT; 59min ago Docs: man:NetworkManager(8) Main PID: 928 (NetworkManager) Tasks: 3 (limit: 76693) Memory: 12.0M CGroup: /system.slice/NetworkManager.service └─928 /usr/sbin/NetworkManager --no-daemon ...
