How to Fix “./install.sh: line 107: rpmbuild: command not found” Error When Installing MailScanner

MailScanner is an open-source email security and anti-spam package that is widely used to protect email servers. When installing MailScanner on a Linux server, you may encounter an error message that says ” ./install.sh: line 107: rpmbuild: command not found”.

[root@mx1 MailScanner-4.84.5-3]# ./install.sh

I am logging everything into "install.log".

Good. You have the patch command.

./install.sh: line 107: rpmbuild: command not found
Your /usr/src/redhat, /usr/src/RPM or /usr/src/packages
tree is missing.
If you have access to an RPM called rpm-build or rpmbuild
then install it first and come back and try again.

This error message indicates that the rpmbuild command is not installed on your system, which is required to install MailScanner.

In this guide, we will walk you through the steps to resolve this error and successfully install MailScanner on your Linux server. We will assume that you have root or sudo access to the server and that you are familiar with basic command-line usage.

Step 1: Install the Required Dependencies

Before installing MailScanner, you need to ensure that all required dependencies are installed on your system. To do this, run the following command:

sudo yum install perl-Net-SSLeay perl-IO-Socket-SSL perl-Time-HiRes perl-Net-DNS perl-IO-Socket-INET6

This command will install the necessary Perl modules that are required to run MailScanner.

Step 2: Install rpmbuild Command

To resolve the “rpmbuild: command not found” error, you need to install the rpmbuild command. To do this, run the following command:

sudo yum install rpm-build

This command will install the rpmbuild command on your system, which is required to build RPM packages.

[root@mx1 MailScanner-4.84.5-3]# yum install rpm-build -y
