Package Management

Updated Mar 27, 2021 ·

Tasks​

  1. Ensure your system is using yum repo for base packages and application streams.
  2. Find the package the contains the sepolicy program file and install it.
  3. Install previous version of PHP
  4. Download http package from repo without installing it. Query to see if there are any scripts in it.

Solution​

1. Using yum repositories​

Check current repositories:

sudo yum repolist

Ensure base repositories are enabled:

sudo yum-config-manager --enable base
sudo yum-config-manager --enable appstream

If they are not listed, you might need to create or modify the repository configuration files. For RHEL-based distributions, the repository configuration files are typically located in /etc/yum.repos.d/.

2. Install sepolicy​

Find the package:

sudo yum provides */sepolicy

Once you identify the package (likely policycoreutils-python-utils), install it:

sudo yum install policycoreutils-python-utils

3. Install specific PHP version​

List available PHP versions:

sudo yum list php --showduplicates | sort -r

Identify the previous version from the list and install it (replace previous_version with the actual version number, e.g., 7.4):

sudo yum install php-previous_version

4. Download http package​

Download the package without installing it:

sudo yumdownloader httpd

Query the downloaded package to check for scripts:

rpm -qpl httpd*.rpm
rpm -qp --scripts httpd*.rpm
