Configure Offline Repository

Introduction

This article describes the configuration of the package manager for a system that does not have access to TelcoBridges repository (no internet access).

Download TelcoBridges repository

Download the ISO image of TelcoBridges repository on a machine that has access to the system.

• Minimal version is here: tb_tbos7_x86_64_repo_minimal.iso (2025.06 1.8GB)
• Full version is here: tb_tbos7_x86_64_repo.iso (2025.06 6.6GB)

Upload TelcoBridges repository to the system

Upload the ISO file to the "/root" directory of the system with scp or a SFTP tool like FileZilla

Mount the ISO file on the system

Mount the ISO file on your system

# mkdir -p /repo/tbos
# mount -t iso9660 -o loop /root/tbos_repo.iso /repo/tbos

Change TelcoBridges repository file

Edit the TB-Base.repo file

# vim /etc/yum.repos.d/TB-Base.repo

Change [tb-base] baseurl line to:

baseurl=file:///repo/tbos

Update packages

# yum clean metadata
# yum update

Delete ISO file

Since the repository file is quite large, it is better to delete it after the update is complete:

# rm /root/*repo.iso
