# Install Trellix Agent 5.8.x on unmanaged Ubuntu systems

Generate a Debian package and install Trellix Agent 5.8.x on an unmanaged Ubuntu system that are not managed by ePO - On-prem. You must manually install the DXL client while installing Trellix Agent in unmanaged mode on Ubuntu system.

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

1. Download Trellix Agent installation package *MAxxxLNX.zip* for Linux from the Software Catalog on ePO - On-prem.

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`

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

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.

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

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