# Offline Repository Procedure for Telcobridges Linux

### 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](https://repo.telcobridges.com/tbos/7/isos/x86_64/tb_tbos7_x86_64_repo_minimal.iso) (2025.07 0.9GB)
* Full version is here: [tb\_tbos7\_x86\_64\_repo.iso](https://repo.telcobridges.com/tbos/7/isos/x86_64/tb_tbos7_x86_64_repo.iso) (2025.07 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](http://filezilla-project.org/)

### Mount the ISO file on the system

Mount the ISO file on your system

1. mkdir -p /repo/tbos
2. mount -t iso9660 -o loop /root/tb\_tbos7\_x86\_64\_repo\_minimal.iso /repo/tbos

### Change TelcoBridges repository file

Edit the *TB-Base.repo* file

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

Change *\[tb-base]* **baseurl** line to: baseurl=file:///repo/tbos/os/$basearch/

### Update packages

1. yum clean metadata
2. yum update

### Delete ISO file

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

1. rm /root/tb\_tbos7\_x86\_64\_repo\_minimal.iso

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://tmediadocs.telcobridges.com/other-pages/operations/offline-repository-procedure-for-telcobridges-linux.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
