Hello, i have created virtual interface on ubuntu 20.04 LTS
but while installing drbl server it does not recognize my virtual interface.
Is there a trick for that problem?
I have removed network-manager and netplan/*.yaml files.
The configs that i used are below.
I will be very appreciated for any helps.

Since it's virtual machine, it's easier you add a virtual network card, not an alias one. Say, you have ens33 and ens34. Then configure them. When running "drblpush -i", it should detect both of them.
Steven
You are right,I can add an extra interface for virtual machine.Could you answer it for a pyhsical computer for educational purposes.
"Could you answer it for a pyhsical computer for educational purposes." -> What did you mean?
Steven
Could you answerthe question for a pyhsical computer?I am asking this question just for learning.
Now you have a Physical computer? You problem you only have 1 network interface, the thing that looks like a really big phone cord. You need at least 2 of them, add a second network card and you will get further.
Looks like you had 2 nics in your VM, but you will need two in the physical computer as well.
as far as i know,It is possible to create virtual nics that is dependent to a physical nic.It is used especially on routers,otherwise a router must have nics as many as subnets.Lets focus drbl server,I have made configurations on ubuntu 16.04 but it is time to upgrade.Ubuntu has changed its network infrastructure with netplan.I have disbaled it and configured like on old days,but i can not succee.If the command outputs are inspected carefully it is very clear what i meant.ifconfig shows virtual interfaces but drbl recognizes only the pyhisical one.That's the problem.
Since you have ens33 and ens33:0, and both of them are configured. What was the issue when you run "drblpush -i"?
Steven
As you see from the only1interface.png attachment. It says only one configured interface found. That is the problem.
Please run this command on the server then post its result:
ip add show
