So I wanted to try out OMV 5 and the setup process worked flawelessly and everything works as expected.
After I run an upgrade (upgrade / dist-upgrade doesn't matter) I lose my network connection.
I expect this to be an driver issue with some newer kernel version, but I am too much of a noob to pin that down exactly.
My network adapter is Realtek RTL8111/8168/8411 (8111 to be exact) and according to this post it needs the rt8168 driver which is only available up to kernel version 4.15.
As OMV 5 is using kernel 5 this obviously doesn't work.
Now the thing is that it all works out of the box when installing OMV.
It installs the rt8169 driver which isn't recommended but at least works.
Until I run the upgrade....
So basically the question is if anybody can help me pin this issue down, so I can tell what part of the update is causing this and how to prevent the update from killing my network.
