# Upgrading Trellix Agent 5.8.x on unmanaged Ubuntu systems

Generate a Debian package and upgrade Trellix Agent 5.8.x on an unmanaged Ubuntu system that is not managed by ePO - On-prem. This option is available only on version 4.8.0 to 5.x.x.

You must have root permissions to install Trellix Agent on the client system.

1. Download Trellix Agent 5.x.x Update X package (such as *MA564XLNX.zip*) for Linux from the Software Catalog on ePO - On-prem where "X" is the update value of the package, for example, Trellix Agent 5.6.4 Update 1.
2. Extract the following installer files to the client system.

### Important

Trellix Agent has removed support for the `mfert` package from version 5.8.2.

  - `mfema-<build_number>.i686.deb`
  - `mfema-<build_number>.x86_64.deb`
  - `mfert-<build_number>.i686.deb`
  - `DXL.zip` file which contains the following installer files.

    - `mfedx-ma-<build_number>.i686.deb`
    - `mfedx-ma-<build_number>.x86_64.deb`

### Note

Use the appropriate `MFEma` and `MFEdx-ma-<build_number>` packages based on the operating systems used. For example:

  - `mfema-<build_number>.x86_64.deb` and `mfedx-ma-<build_number>.x86_64.deb` for a 64-bit operating system
  - `mfema-<build_number>.i686.deb` and `mfedx-ma-<build_number>.i686.deb` for a 32-bit operating system.
3. Open **Terminal**, then enter the path where you have extracted the installer files.
4. Run the following commands:

  - For a 64-bit operating system:

```
dpkg --install mfert-<build_number>.i686.deb
dpkg --install mfema-<build_number>.x86_64.deb
dpkg --install mfedx-ma-<build_number>.x86_64.deb
```

  - For a 32-bit operating system:

```
dpkg --install mfert-<build_number>.i686.deb
dpkg --install mfema-<build_number>.i686.deb
dpkg --install mfedx-ma-<build_number>.i686.deb
```
