OpenEMM Technical Support Forum

i have a setup on centos 8 and made a new install based on the install guide.
when i start the installer, i get the message that there's an update available with no choice to cancel it.

the installer restarts and fails with following message:

Checking python installation ...
Python version found: 3.8.6

DB version found: mysql Ver 15.1 Distrib 10.3.17-MariaDB, for Linux (x86_64) using readline 5.1

Starting python ...
AttributeError: type object 'Environment' has no attribute 'emmStatisticsPropertiesFilePath'


any ideas how to continue?

I've got same problem. Hope someone can give an advice.

Which version of the runtime did you use?

JAVa version use:
/usr/lib/jvm/java-11-openjdk-11.0.8.10-0.el8_2.x86_64

$cd /home/openemm
$ tar zxvf openemm-runtime-20.04.000.043.tar.gz

$sudo su -

Thanks for your feedback!

Please use the 20.04 installer to install OpenEMM 20.04.

OpenEMM 20.10 ist still beta and the 20.10 installer (also beta) is not ready yet to install OpenEMM 20.10 from scratch withut having installed OpenEMM 20.04 before.

I'm using 20.04 installer , still same error , even if I don't select the latest version to upgrade.

Hi maschoff,
Have you got a chance to take a look on this error?

Thanks

Dou you have a runtime 20.04.000.050 installed where you can switch to? If not, install it from our Cloud (menu "Install or update package from AGNITAS Cloud") here:

Hm, we can not reproduce this out of the box. Am I right that you have a clean CentOS8 server and you try to do a new OpenEMM installation with the runtime package from the AGNITAS website and your /home/openemm directory was clean before?

Hi Maschoff ,
Yes that's correct, i would guess same issue having by 1100101

Regards

OK, we will look into that.

Problem is fixed in OpenEMM Runtime version 20.10.039, which is now available.

Thanks aso,
can you please try 1100101 if it works for you
I've tried using the version mentioned and still same problem, I probably need to redo my Centos 8 installation and prerequisites.

Regards

FYI: We are already at runtime 20.10.052. Maybe it makes sense to retry with a later version.
