Zend Server 8.x
Linux (Specifically Reported under CentOS 7)
Current CentOS 7 image for Docker
Zend Server 9.0
When installing Zend Server using the Linux installer, you might get this error:
"Your system doesn't support either dpkg or rpm"
When running uninstall.sh to remove Zend Server, you might get this error:
"/usr/local/zend/bin/uninstall.sh: line 66: which: command not found"
Install 'which' command and run the installation / uninstall again.
This was resolved in Zend Server 9.0, by removing dependency of 'which' package from installation scripts.
