computershateme commented 2 months ago

Describe the bug Graphical Interface partially connected to wired ethernet

To Reproduce

  1. Install KDE desktop
  2. Install NetworkManager
  3. Login to Graphical Interface using either X2Go or RDP
  4. Open terminal and type multipass networks and see list of available networks
  5. Hover over the "Networks" icon on the bottom right of the screen and see "Disconnected"
  6. Right click on "Networks" icon and select "Configure Network Connections"
  7. Click + sign ("Add new connection") and select "Wired Ethernet"
  8. Click dropdown on "Restrict to device" and select a network connection, click "Random" on "Cloned MAC address" line
  9. Click "IPv4" tab and put check in box "IPv4 is required for this connection
  10. Click "IPv6" tab and put check in box "IPv6 is required for this connection"
  11. Click "Save"
  12. Enter sudo systemctl restart NetworkManager && sudo systemctl restart dbus.service && sudo systemctl restart polkit.service"
  13. Again click on "Networks" icon and see "No available connections"

Hi @computershateme Thanks for reporting this. Before we can dig deeper, I think we need more clarification of some information. Your OS is Mac Sonoma and the local driver is lxd, however Multipass does not support lxd on that platform as far as I know.

Is there something we are missing?

computershateme commented 2 months ago

Apologies (I should have double checked which terminal window I was typing the command into), here is the correct information:

georgeliao commented 2 months ago

@computershateme Not sure I fully understand the scenario, about the first three steps, are you using a local machine to access a remote macOS machine?

computershateme commented 2 months ago

Hi there. The Mac is my local machine and I am remoting into a plasma desktop I created using multipass. I am able to remote into the desktop using RDP and X2Go.

Once I am in I can use my web browsers and Synaptic Package Manager with no problems. When I try to use the "Update" features in the Snap-Store and Software apps it says that there is no network connection. When I open the Network app there are no network connections. When I create one, it doesn't stick.

When I run multipass exec -- bash -c 'ip -c -br 1'on my Mac, it tells me that the multipass bridge mpbr0 is down and says in the last column <NO-CARRIER, BROADCAST, MULTICAST, UP>.

Hi @computershateme,

We are very puzzled in how you are seeing the Multipass bridge mpbr0 on a macOS based Multipass install. This should only show up when running Multipass on a Linux host and see mpbr0 on the Linux host or running it in a nested environment, ie, a macOS host running a Linux VM running a Multipass VM. On a macOS host, you should never see mpbr0 when issuing multipass networks and how you see that is not clear to us.

Could you please give the full environment of your set up, ie, your macOS host (Apple silicon vs. Intel), any VM's through a different virtualization manager, how you have you Multipass instance set up, etc. Any and all details will be very helpful in helping you either diagnose what is wrong or determine if you running Multipass in an unsupported manner.

Thank you!

There's definitely a reason I picked "computers hate me" as my username.

I am running a Mac mini M1. In Parallels I have Ubuntu, Windows 11, and Arch Linux VM's installed. I also have VMWare Fusion installed and have a Windows 11 machine. In UTM I have Windows 10 ARM, Windows 11, and Manjaro Linux VM's. I have VirtualBox but none of those VM's work. Finally, I have Multipass installed.

The mpbr0 might be from my installing multipass inside one of my instances (I figured that it would be fun to make instances inside instances).

I'll try removing the multipass from inside the instance and seeing if the mpbr0 disappears...I'll let you know.

computershateme commented 2 months ago

Yup, mpbr0 is gone

computershateme commented 2 months ago

Ok, so here's where I am now. Just from deleting multipass that I installed in my instance, the networks are showing up and are showing as connected, but are saying the connection speed is 0 Bit/s. Image 4-28-24 at 2 10 AM

townsend2010 commented 2 months ago

Hi @computershateme!

You say they are showing up, so are they working? The lack of connection speed may just be an artifact of it connecting through a bridged interface. I will say that it sounds like you are doing things that we have not done :sweat_smile:

computershateme commented 2 months ago

Haha I'm all about being different. I feel like we're getting closer because now the networks are showing up in the network area. I'm still able to get to the internet via the web browsers, but the problem remains with the programs that integrate in with the desktop as they are still not connecting with the network.To draw a parallel, I feel like the main water pipe is open but, for some reason, none of the sinks on the second floor have running water.Sent from my iPhoneOn Apr 29, 2024, at 4:02 PM, Chris Townsend @.***> wrote: Hi @computershateme!

Hi @computershateme,

Unfortunately, I'm not really sure what else we can do here. We don't prevent users from installing desktop environments (and we really couldn't if we wanted to), but we don't provide any official support for that. You seem to be in uncharted territory :slightly_smiling_face:

I'm going to close this, but feel free to reopen or open a new issue if you can determine that something we're doing in Multipass is at fault. Sorry we couldn't be of more help.

computershateme commented 2 months ago

I am wondering if it has something to do with the bridge and the way multipass is treating each session.

When I multipass shell or ssh into an instance and run loginctl list-sessions, I see a bunch of sessions...even ones that aren't being used any longer. I will then clean that list using loginctl terminate-user.

Once I know that all sessions are closed, I will ssh -X into the user instance and will see a similar problem even with just -X forwarding.

townsend2010 commented 2 months ago

The sessions you see are due to the tray icon GUI having to poll the daemon to get near real time info about instances which uses SSH to get this info. It's not ideal, but it works and the upcoming 1.14 release makes this much, much better.

townsend2010 commented 2 months ago

I will say it seems like networking works except for some apps in the desktop session, but other apps that use the network will work. I don't know the internals of the desktop environment enough to venture a guess at what it is missing.

computershateme commented 2 months ago

Then I'm super excited for 1.14 :-)

I'll try the Ubuntu board to see if they know how to clear the desktop issue.

Thanks for your help :-)
