Resolved:
In emergency mode (without network and GUI) I started update again. There were a lot of error or warning messages for files:


zypper --no-refresh dup
...
Aditional rpm output:
/sbin/ldconfig: File /usr/lib64/libmicrohttpd.so.12 is empty, not checked.
...

After that is possible to mount /home and restart is normal. BUT, after few second I see gnome login screen, and again, again…
In text mode I tried zypper dup without success (over 200MB was doanloaded and I saw a lot of errors and warnings).
So, last command for reinstalling packages helps me. Thanks for https://unix.stackexchange.com/questions/299548/how-to-reinstall-all-installed-packages-with-zypper


sudo zypper in -f $(rpm -q -a --qf '%{NAME} ')

I’m going to check virtual machines, VPNs, …

Thanks for support.

Bye
