Hi everyone,
I’m trying to install webtop5. I read in the old posts but I didn’t understand what I should do.
I use NS 7.3.1611 (Final) and run webtop4.
I tried uninstalling webtop4 and installing webtop5, but I received incompatibility errors from YUM libraries.
Is there a cheklist to do, to follow?
Thank you

I have a fresh installation of nethserver. I added a webtop 5 with no errors. After login with admin/admin only blank page opened. In a log I see couple errors, but have absolutely no idea what I can do about it.

Can someone help?
Hi Alex,
you can try to run this event:
signal-event nethserver-webtop5-update
and see if the problem is solved?
Tried that. In the log I see that nothing upgraded:
2017-05-03 16:02:29 [INFO ] c.s.webtop.core.app.ServiceManager - Not upgraded! [5.0.0 = 5.0.0]
(several messages). After than two warning messages:
2017-05-03 16:02:34 [WARN ] c.sonicle.webtop.core.app.WebTopApp - No configuration found for TomcatManager [tomcat.manager.uri]
2017-05-03 16:02:34 [WARN ] c.sonicle.webtop.core.app.WebTopApp - Webapp version automatic check will NOT be performed!
And three java errors (very long. I’ll post them if necessary)
Anything else?
Is there some pre-installation requirement for webtop5? I assumed (as far as package is included in server approved software), that it will install all necessary dependencies. And this is not my first unsuccessful installation of webtop5. First I tried to install it on server, which has been updated (several times) from alpha. This time I made a clean installation from final release with no errors during installation (unfortunately also unsuccessful). What am I doing wrong?
Did not help. Nothing updated (in the log), two warning in the log about tomcat configuration and three Java errors after admin login. And blank screen on the web page.
