Hi!
Right now there are like 3 (known) problems that can cause loss of network connectivity.
- Running under a VM with a VMware specific NIC. I would not be surprised you could have the same problem with other VM solutions though…
- Having some types of DAHDI hardware. The ones which seem to be causing problems right now are the ones who appear like network cards to the system once their drivers are loaded.
- In some situations having IPv6 activated on your system.
I don’t think it’s that easy in this case since this problem was reported early on by one of the early testers (ie @waldrondigital) over a month ago.
I was one of those early testers and had the loss of network connectivity problem but in my case early on it seemed to be related to my DAHDI card which, once it’s drivers are loaded, appears like a network card.
(I could not say with certainty until very recently…)
Back when I ran the distro upgrade “script” there were other issues with those DAHDI drivers and the ones specific to my card (Wanpipe drivers for my Sangoma A200) and it looks like this might actually have helped in some ways because I think it might be once those DAHDI drivers got updated/moved out of the way that my system network connectivity was restored.
I still had a problem which was causing a slow but for me but lost of network connectivity for others which I thought I fixed this week but I had a weird problem today so I am not sure anymore.
Each time someone reports a network connectivity problem my first two questions are “Are you running a VM and do you have DAHDI hardware?” because, early on, this seemed to be what was tying those network connectivity problems together…
(It’s actually me who referred @mattbratt to the post he referred you too like a day or two ago… )
I believe the network connectivity test is actually in response to the network connectivity problems @waldrondigital and me had that this test was added to stop the upgrade as soon as the problem was noticed…
I have not played with VMs in quite a while but Iwould not be surprised it would a missing driver thing and that they might not be allowed to distribute the VMware one or something like that…
What I guess they could do is try to detect your network card is setup like this and tell you to change before allowing the script to run further.
As for IPv6, someone reported having IPv6 activated was causing him DNS issues and those tend to look like network connectivity problems even though it is something only name resolution problems…
Of those problems, as an early tester, I only had one but had quiiiiite a few others, most of which have been fixed…
Good luck and have a nice day!
