<div class="">Either "added a single line to the .cc file in the scratch folder" or "Our complete setup was working without any issues before adding this line" is false.</div>
<div class="">Did you perform any of the following actions?</div>
<div class="">
<ul class="">
<li class="">Upgrade or downgrade ndnSIM (e.g. git pull)</li><li class="">Upgrade or downgrade the scenario template</li><li class="">Upgrade or downgrade the ndn-cxx or NFD submodules</li></ul>
</div>
<div class=""><br class="">
</div>
<div class="">Most likely, one of the above is not ndnSIM v2.0, but a later version.</div>
<div class="">"LocalControlHeader" is present in ndnSIM v2.0 (released 5 years ago), but deleted in later versions.</div>

<div style="" class="">My research group had a scenario using ndnSim2.0 and it was running all good. I made a simple change to the scenario (added a single line to the .cc file in the scratch folder) and now when I try to run the scenario, it throws errors.
Our complete setup was working without any issues before adding this line. Here are the error messages and I am not sure why a previously working system is throwing these errors.</div>
