Hi ksar,  
thank you for your reply, is this mean Dolibarr new versions will work only on ubuntu? and every time i need to upgrade i have to run your proposed workaround?

Hi!  
For upgrading only you don’t need to install the entire deb package. Just copy needed files into your www/html/dolibarr/… directory. Dolibarr will automatically detect and bring you to the update page.  
Please make sure to rename the “install.lock” file in the documents folder.
