Requires: devtoolset-8-toolchain

Environment

• CloudLinux OS 7 Shared Pro
• Acronis

Solution

1. Install/update the following package:

cloudlinux-scl-release

It should connect the required repositories for the installation of llvm-toolset.

Check if there are cloudlinux-scl-release's files are missing:

# rpm -ql cloudlinux-scl-release
# rpm -V cloudlinux-scl-release

If so, and if the issue persists, reinstall cloudlinux-scl-release:

yum reinstall cloudlinux-scl-release
