cannot save settings (#17781)

[ModEdit; related ticket: #17781: "Failed to save settings" for registered VM if HostNetwork or NATnetwork is not available in new host]

Hi

I have Ubuntu 16.04 host (64 bit) and a windows 7 guest (64 bit).

Recently I started having problem making changes to the settings of the guest VM. This is the error I get when I try to save the settings:

Any idea how to fix this?

Please attach images locally. Even better, COPY the error message and post the text. Much smaller, copyable, searchable.

What has changed on the host between when you last remember it working and now?

My crystal ball is currently broken. If you want assistance you are going to have to give me all of the necessary information.
Please don't ask me to do your homework for you, I have more than enough of my own things to do.

Go to the VM settings » Network. Check your network adapters, all 4 of them, even if they're disabled, to see that they don't point to something non-existent.

If they do, even if they're disabled (that's a bug soon to gain a ticket number), enable them, make the changes needed to make them valid and then disable them again.

If you can't figure it out, right-click on the VM, "Show in Explorer/Finder/something". ZIP that selected .vbox file and attach it to your response.

BTW, did you create that VM locally, or did you import it from another host?

WOW! That was it! The second tab, although disabled, was attached to something. I made it "Not attached" and the problem is gone.

Thank you so much.

That's exactly what I referred to earlier as "that's a bug soon to gain a ticket number". I've discovered that issue when copying VMs between hosts. Although disabled, a previously configured HostOnly, or NATservice network, that doesn't exist on the new host, will trigger this bug. If the adapter is enabled, it will trigger a warning about the non-existent network. If it's disabled, it should definitely not react like that, but simply revert to "Not Attached".

I talked with the developers earlier this morning (since you actually reminded me to file that bug report), and I did point them to your post. They said that it's not a 5-minute fix, and I need to file a ticket, not to solve it over IRC... ;)
