Try installing software-properties-kde and get
The following packages have unmet dependencies: software-properties-kde : Depends: python3-software-properties (= 0.96.24.32.11) but 1.8.8 is to be installed E: Unable to correct problems, you have held broken packages.
Try to install python3 from the bionic from bionic-updates
sudo apt install -t bionic-updates python3-software-properties
Install software-properties-kde
sudo apt install software-properties-kde
If it fails try force installing it
sudo dpkg -i --force-overwrite /var/cache/apt/archives/software-properties-kde_0.96.24.32.11_all.deb
Install Kubuntu desktop
sudo apt install kubuntu-desktop
First add the following repo
sudo add-apt-repository ppa:kubuntu-ppa/backports
Make sure you are updated and upgraded
sudo apt-get update && sudo apt-get dist-upgrade
And if needed do a reboot
sudo reboot
Install the KDE desktop
sudo apt install kubuntu-desktop
Log out, select Plasma and log back in.

Install dhcp server software
sudo apt install isc-dhcp-server
Edit the following config file and set the networking interface it should use. In this case enp60s0
sudo vi /etc/default/isc-dhcp-server
Example line to change
INTERFACESv4="enp60s0"
Now edit the dhcpd.con file
sudo vi /etc/dhcp/dhcpd.conf
Add the following in. Change the addresses and settings as needed.
subnet 192.168.47.0 netmask 255.255.255.0 {
range 192.168.47.26 192.168.47.30;
option domain-name-servers ns1.internal.example.org;
option domain-name "internal.example.org";
option subnet-mask 255.255.255.0;
option routers 192.168.47.1;
option broadcast-address 192.168.47.255;
default-lease-time 600;
max-lease-time 7200;
}
Set a static ip on the computer that’ll be acting as the dhcp server. You can set it as the gateway if it is the gateway.
Allow dhcp through the firewall
sudo ufw allow 67/udp sudo ufw reload
Restart the service and connect a client.
sudo systemctl restart isc-dhcp-server
You can look at dhcp leases with the following command
tail -f /var/lib/dhcp/dhcpd.leases
Install iperf
sudo yum install iperf3
Launch server with
iperf3 -s
If you want you can have it bind on a certain interface which can be useful in some causes if you have multiple IP addresses on the system. The IP address is the local address of the machine.
iperf3 -s -B 192.168.1.1
Note you may need to disable the firewall to allow access from the client
sudo systemctl stop firewalls
From the client computer install iperf and run it.
iperf3 -c 192.168.1.1
Boot up and create your raid array
Boot into Clonezilla and get to command line :cry: unfortunately you can’t clone from disk to raid in clonezilla interface, however we can do it from the command Line!
Basic steps are as follows. Replace raidarray with the name of your raid array.
sudo apt full-upgrade
When prompted type in the following to continue the upgrade
Yes, do as I say!
You may need to remove libsnmp-base if you have package issues.
sudo apt-get remove libsnmp-base
Install crunch and then generate a word list with the following command. The 8 8 tells crunch to generate combinations that have a minimum and maximum length of 8. All the numbers from 1-0 tells crunch to use these characters, -o writes to output file.
Change options if desired.
crunch 8 8 1234567890 -o 8numberchars.lst

Doing a port scan on the 50000-59999 port range reveals all the connected subscriber modules.
Alfred@localhost:~$ nmap -p 1-65535 10.0.0.2 Starting Nmap 7.60 ( https://nmap.org ) at 2019-09-30 23:55 CDT Nmap scan report for 10.0.0.2 Host is up (0.026s latency).

Should be able to access the login page for the subscriber module by going to https://enodb-ip:xxxxx
Where xxxxx is the port number from the scan. Should be 5 with the last four IMSI numbers of the subscriber unit.
Based upon multiple nmap scans on Baicells eNoceB’s it appears that they use port 27149 as the default SSH port.
Example scan
