I was able to configure and make using these lines.

apt remove libssl-dev; apt autoremove
apt install build-essential libncurses5-dev libssl1.0-dev

wget 'http://ftp1.digi.com/support/driver/81000137_Y.tgz'
tar -xzf 81000137_Y.tgz
cd dgrp-1.9
wget -O '0000-Kernel-4-13-CLASS_ATTR_STRING.patch' 'https://aur.archlinux.org/cgit/aur.git/plain/0000-Kernel-4-13-CLASS_ATTR_STRING.patch?h=dgrp'
patch -Nup1 -i '0000-Kernel-4-13-CLASS_ATTR_STRING.patch'

wget -O '0001-Kernel-4-15-timers.patch' 'https://aur.archlinux.org/cgit/aur.git/plain/0001-Kernel-4-15-timers.patch?h=dgrp'
patch -Nup1 -i '0001-Kernel-4-15-timers.patch'

One can email tech support and ask for the newest beta driver. I have it working on Fedora 28 and Ubuntu 18.04

We have the same problem on an ubuntu 18.04 server (Linux S18028 4.15.0-22-generic)

I don't really understand how to use the patch, can you just send us some explaination ti use it and solved the problem, many thanks for your help.

Best regards,

Email tech support and see if they will send you the newest Beta RealPort driver.  I have it working on 18.04 myself.

to support Ubuntu 18.04. You can get my updated
version here:
