I am very sorry if my simple questions annoying you. Really sorry for that.

So the problem package is Code: libx2go-server-db-perl That is not installed in ordinary ISPConfig installations. If you do not need it, purge it away. Or configure it properly so that error goes away. By the way, my Debian 9.6 does not have package libx2go-server-db-perl available. Where was it installed from?
There is probably way to reset the statoverride, though I don't know how off the top of my head; as a workaround, you could probably create x2gouser group and see if dpkg continues, then ensure that group is removed after you purge your x2go packages, if you are doing that.
Finally, problem solved! Thanks for everyone who had contributed to this issue and thanks to till for making this place for people like us. After using that long command (./configure ...) for hundreds of times and solving each issue that comes to me it solved. Unfortunately, I don't remember how many packages installed, reinstalled or updated but it worked for me. I don't know if there is a command to list my history here to share with contributors and friends. Thanks and Love Asghar
You can see in /var/log/dpkg.log what packages were installed or removed. And terminal may have lines stored when you scroll up, and there is command history that shows what is in history buffer.
I picked up all necessary logs for the last day configuration. Please check out the attachment. Even I didn't figure out how could I did that.
