Public bug reported:
On my machine (OPTIPLEX GX620, Xubuntu 18.04 LTS) my wired (Ethernet)
connection disconnects randomly. Everything was fine before the upgrade
from Xenial LTS. It's not yet reproducible (by me). There are no error
messages associated with it, the indicator plugin doesn't turn grey, and
I've noticed no pattern to when it occurs. The only way I know it is has
occurred is when something that uses the (Samba) network times out or
stops doing anything. If I click the indicator plugin and select "wired
connection 1", it reconnects immediately, But at some later time the
same thing may happen again; it could be after a few minutes or many
hours. This happens on another, the AMD machine I use as a file server,
too, so it looks like a bug in Bionic Beaver, not a software package.
lsb_release -rd
Description: Ubuntu 18.04.1 LTS
Release: 18.04
I suppose the bug could have something to do with the compatibility of
Samba and 18.04 LTS, because after the upgrade, everything in /etc/fstab
that used the credentials option stopped working, but that's part of
another bug already reported by others but not yet solved.
