Need help to upgarde Dolibarr to 15.0.3 from 15.0.2

Hi @ksar !

Thank you for your answer !

I think I have unpacked the file well.
I tried: unzip dolibarr-x-x-x.zip and cp -r dolibarr/* /var/www/mydolibarr/
and unzip dolibarr-x-x-x.zip -d /var/www/mydolibarr/

Is there an error with this logic?
Thank you !
