** Description changed:
This is the same bug I notified at Bug #1770848 but with a more precise
selection of (what I think it is) the package affected and a better description.
I made a few days ago a fresh install of the Kubuntu 18.04 LTS and it is
most everything Ok, but -I think that- the network-manager has a
problem.
In the last LTS version, Kubuntu 16.04, nor in any Linux version if I
remember well, I never lost connection through Ethernet (the only
Internet connection with our desktop PC), but the Bionic Beaver loses
the connection every now and then, perhaps within few minutes or hours,
but several times per day.
When the connection is lost, I note that it disappears any info even
mention to any network into the network window and the network manager
icon becomes red color.
Not matter if I unplug and then plug the ethernet cable again, the
ethernet connection is not longer detected and only restarting the PC
makes the connection to work again.
Incidentally, I also have noticed with this version of Kubuntu 18.04
that in my laptop there is also now a similar problem with the scanner:
If I plug it in some USB port of the laptop once Kubuntu 18.04 is
already running, it's not detected by Xsane. I have to plug it in before
than pressing the power button or at the time of starting the OS, for
the scanner to be detected by the scanning program (and then only works
with Xsane, not if I use Simple Scan or Skanlite, even when it works
under Xsane), as I said in the Bug #1771525 and, evenly, if I unplug the
scanner cable from the USB port it is not detected anymore when plugging
it again, and only restarting the laptop makes it to be detected.
