Thank you that you help me.
Now I began new installation on debian stretch on yours instructions.
After start of scripts I receive the message:

root@tce:~/builddir# ./x2goconfig && ./x2gousbpatch && ./x2gobuild 2>&1 | tee logfile
One or more of the following variables is unset:
LBX2GO_ARCH: ''

LBX2GO_TIMESTAMP: '20190114120404'
