Webadmin Internal Server Error

[mike59999]

Hi,

we have upgraded our Zentyal Installation from 3.5 to 4.0 today.
All Moduls are working but the Webinterface is no longer reachable.
As soon i connect to the Webinterface i get the message "Internal Server Error".
There are some erros in the Logfile "zentyal.webadmin-uwsgi.log" that is attached in this thread.
Can someone help us to get the Webinterface running again?

With best regards,

Michael Darsane

EDIT: A Bugtrackerticket is open under https://tracker.zentyal.org/issues/2456

I have found a work around for the moment, it's not the perfect solution.

1. Open the File "/usr/share/perl5/EBox/WebAdmin/PSGI.pm"
2. Go to the end of the File and remove the following part.

    if ($@) {
        throw EBox::Exceptions::Internal("Cannot load $pkgName: $@");
    }


3. Restart the Webadmin Service with "/etc/init.d/zentyal webadmin restart".

The modified file is in the attachment.

Removing that only hides the real error, it's not a proper fix.

Please we need the contents of /var/log/zentyal/zentyal.log (and probably also /var/log/zentyal/error.log) to see the real error in order to diagnose it and fix it.

This has to be some corner case because in all our tests the upgrades have been successful.

Here is the logs from one of our servers with the issue. Hope it helps

I do also have the same problem. Upgraded today and only I only get Internal Server Error in the Admin Web administration.

But I did the upgrade thru the Webadmin console.

Yesterday I've got the Webadmin Internal Server Error after I installed some new Softeware-modules in Zentyal 4.0. (Modules "Mail an Groupware" and "Openchange")

First I did the dirty fix removing the line 

Code: [Select]

if ($@) {
        throw EBox::Exceptions::Internal("Cannot load $pkgName: $@");
    }
and my Webadmin-Inerface worked well.

But today I've looked at the Zentyal-Error-Log and the Error was:

Code: [Select]

2015/03/04 15:37:50 [error] 22373#0: *1 open() "/usr/share/zentyal/www/images/package-icons/zentyal-common.png" failed
