### TelcoBridges repository

The operating system software upgrade is performed using *yum* software package manager. The repository sites providing RPM packages are configured from /etc/yum.repos.d/. TelcoBridges provides its own repository of operating system files (<http://repo.telcobridges.com>).\
On a High Availability 1+1 system (HA), this procedure needs to be done on both primary and secondary systems.<br>

If the unit or Linux server does not have access to Internet (or does not have DNS configured), you should configure an offline repository on your local machine as explained in the section below.

* [Configure a local offline Repository for Telcobridges Linux](https://docs.telcobridges.com/wiki/Configure_Offline_Repository)

### Operating system software packages update

The operator can use one of the two methods available: The Web Portal (GUI) or command line interface.

#### Web Portal

To upgrade software packages, follow this procedure from the web interface of the unit:

* Hosts -> Status -> TBxxxxxx -> Action -> Upgrade Linux Packages, then 'Apply Action':

When the upgrade is in progress, no status is shown. You will see a similar screen:

<figure><img src="https://docs.telcobridges.com/w/images/a/a0/Upgrade_Linux_Progress.jpg" alt=""><figcaption></figcaption></figure>

It may take up to 8-10 mins. You need to refresh the page until you see this:

Once complete, reboot the host: Hosts -> Status -> TBxxxxxx -> Action -> Shutdown -> Reboot

#### Command line

Alternatively, you can ssh to the unit and run the following command:

```
# yum clean all
# yum update
```

Reboot the unit

```
# reboot
```
