Issue with MadAnalysis5

Hi,

I have a problem with Madanalysis5.
I use Ubuntu 20.04 LTS.

When I want to use the program, after I launch it with the ./bin/ma5 command, I get the following error :
(by the way, In this generated error report," commande introuvable" means command not found and "aucun fichier ou dossier de ce type" means no such file/folder found. )

make : /home/sofia/madanalysis/tools/SampleAnalyzer/ExternalSymLink/Bin/root-config : commande introuvable
g++ -Wall -O3 -fPIC -I/home/sofia/madanalysis/tools/ -o root/TreeReaderBase.o -c root/TreeReaderBase.cpp

From what I understand, this may be an issue with ROOT.
Does anyone have an idea of how I Could fix the issue ?
Maybe I could disable ROOT, but how to do it, exactly ?

Thanks in advance for your help.
