Which version of SuiteCRM are you trying to Install?
I believe this was an issue on much older versions, but I haven’t seen it at all, more recently
Having a look around, it seems like the consensus is that this was down to the file/folder permissions being incorrect:
So I would suggest ensuring that the file/folder permissions are set correctly before proceeding with install.
We usually suggest:
sudo chmod -R 755 .
sudo chmod -R 775 cache custom modules themes data upload
sudo chown -R www-data:www-data .
(replacing www-data with whatever your web server user is)
