tested installation after latest updates of webproxy,openvpn and bandwidth: install with no error
but ntopng seems to fail when enabled:
ov 26 16:45:14 ns79rc1b systemd: Failed at step EXEC spawning /usr/local/bin/ntopng: No such file or directory
Nov 26 16:45:14 ns79rc1b systemd: Unit ntopng.service entered failed state.
Nov 26 16:45:14 ns79rc1b systemd: ntopng.service failed.
I know, but it should be fixed with: Access web applications from port 980 · Issue #6344 · NethServer/dev · GitHub
Could you please verify to have the versions listed in that comment?
sorry, yes i had already checked, same versions
n2n-2.8.0-539.x86_64
ndpi-3.4.0-2929.x86_64
ntopng-data-4.0.200525-9255.noarch
ntopng-4.2.201125-11566.x86_64
pfring-7.8.0-3283.x86_64
Thank you! Is there anything relevant inside /var/log/messages or journalctl -u ntopng?
not so much:

but ntopng seems to be in /usr/bin/ntopng , so i changed the ExecStart in ntopng.service, and it seems to work, or at least it starts
Sorry for the late response, I took a day off 
This indeed a bug: https://github.com/NethServer/dev/issues/6350
It was a changed asked by me to upstream, but I didn’t expect that it could land so soon inside the release.
I’m going to fix it, thanks for reporting!
Also I would like to ask: did you notice an increased CPU usage from the new ntopng page?
