Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 19.1 and the Intel® Quartus® Prime® Pro Edition Programmer and Tools version 19.1, you may see this error when launching the GUI using the Intel Quartus Prime Pro Edition software or Intel Quartus Prime Pro Edition Programmer and Tools in the Linux environment.
This error occurs when you install the software using a login in Linux group A and you use the software using a login in Linux group B. For example, the issue occurs if the software is installed with root or sudo privileges and the user is in another Linux group that does not have those privileges.
To work around this problem, follow the steps below:
cd to <quartusroot dir or standalone programmer rootdir>
sudo find . -perm 750 -exec chmod 755 {} ;
sudo find . -perm 550 -exec chmod 555 {} ;
sudo find . -perm 640 -exec chmod 644 {} ;
This problem is fixed starting with the Intel® Quartus® Prime Pro Edition Software version 19.2.
