Re: [sumo-user] 503 error on sumo.dlr.de website
Please find attached the first lines of the file.
After "<?xml version="1.0" encoding="UTF-8"?>", the following lines are commented and the file continues with "<additional xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://sumo.dlr.de/xsd/additional_file.xsd">" and so on.

With regards,

Thank you so much for your answer Jakob,

I have tried all the alternatives with no success.

In fact, for the first alternative, this is what I had already done for the first time. Changed <routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://sumo.dlr.de/xsd/routes_file.xsd"> to <routes> for the route file for example. The simulation ran very fast, but couldn't end, instead it throws a 139 exit code I have explained in my previous answer.

For alternative 2, I don't really know how to add this option when running sumo. In fact, I am running it with its script in the veins package in the Linux command line like this ~/src/veins-veins-4.7.1/sumo-launchd.py -vv -c /usr/bin/sumo. Maybe by running sumo with sumo-gui or sumo, I could add this option but not with the script I am using.

For alternative 3, the SUMO_HOME environment variable were already set, so nothing has changed.

The figure below shows the exact error I am getting

And when I open the link directly in my browser, I get this message "This XML file does not appear to have any style information associated with it. The document tree is shown below.

Hello,
commenting out the schema information in the xml file cannot work because you cannot comment out the root element. Instead you need to look for the attribute called 'xmlns' and delete it like this:

before:
<routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://sumo.dlr.de/xsd/routes_file.xsd">
after:
<routes>

Alternatively 2: add the option '--xml-validation never' when running sumo.
Alterantive 3: set the SUMO_HOME environment variable to point at your SUMO folder so the schema files can be looked up from SUMO_HOME/data/xsd

Jakob

Oh no! I have spoken very fast.

In fact, I am now able to launch my simulations (faster though) but the simulation ends with a 139 exit code on omnet++ (a segmentation fault error). When I try to debug the error on my IDE, I can clearly see that the missing files (the schemas I have commented out) are mandatory because the error points on a "missing" file twice in the code.

Please is there a way for me to run sumo without using the schemas of sumo.dlr.de website? I have tried to use a map from openstreetmap and transformed it to a network using
netconvert
and avoiding using any "online" schema but I got an error.

Any help will be really appreciated, I can't do anything.

With regards,

Thank you very much for your answer Jakob,

In fact I am using the poly.xml file of sumo.dlr.de and I am getting this error: "Error: unable to connect socket for URL 'http://sumo.dlr.de/xsd/additional_file.xsd".
I have carefully read the instructions here  http://sumo.sourceforge.net/userdoc/FAQ.html#What.27s_the_deal_with_schema_resolution_warnings_.2F_xsd_errors.3F and commented out all the schemas and everything is now running like a charm. Thank you once again.

With regards,

Sorry for that!
The error is on our end and we are still working feverishly to get it fixed by the responsible party.
While the outage lasts, you can use our backup wiki at http://sumo.sourceforge.net/userdoc/
If your simulation does not run because the schema files cannot be downloaded from the website there are several solutions outline here: http://sumo.sourceforge.net/userdoc/FAQ.html#What.27s_the_deal_with_schema_resolution_warnings_.2F_xsd_errors.3F

Hello everyone,

Since almost 6 months, I am using Sumo 0.32.1 on ubuntu 16.04 as my traffic generator coupled to Veins-4.7.1 and omnet-5.4.1. Until the mid of January, everything was really good but from the end of January until now, I am not able anymore to access the website http://sumo.dlr.de. As a result of this, I can not use any of sumo files integrated inside my simulation pack (any .xml file: mytype.poly.xml for example).

I read considerably on this error and I concluded that it may be something related to a bad configuration for https. I have to mention that I didn't change anything from the moment everything was good to the moment things went wrong. Anyway, I have successfully installed ssl self-signed certificates and configured everything. But nothing changed. I used another computer and I faced the same problem. So my questions are:

1) What am I doing wrong now? Am I the one who is causing that or the website has changed? Please is there something I could do in order to get rid of this error and go forward with my simulations?
2) Is the new release of sumo (1.1.0) mandatory to successfully use sumo now?

Thank you in advance.

Best,
