Ensure weak dependencies are configured

低级别 2自动化linux

说明

The RPM packaging specification allows for 3 levels of dependencies to be declared: • hard dependencies (Requires / Provides) for packages which must be installed for a minimal installation of the application to function • weak dependencies (Recommends / Supplements) for packages which provide additional features, but which are not required for a minimal installation to function • hints (Suggests / Enhances) for packages which offer add-ons which might be useful.

修复方式

修复方法: 操作指南或基础设施补丁

Edit /etc/dnf/dnf.conf and set install_weak_deps=0 in the [main] section. [main] install_weak_deps=0 Example script: #!/usr/bin/env bash { if grep -Pq '^install_weak_deps' /etc/dnf/dnf.conf; then sed -i 's/^install_weak_deps\s*=\s*.*/install_weak_deps=0/' /etc/dnf/dnf.conf else printf '%s\n' "" "install_weak_deps=0" >> /etc/dnf/dnf.conf fi }
