# Enterprise Qt Debian Packages

To use Enterprise Debian packages with Qt, add your enterprise repositories to Advanced Packaging Tool (APT). For details, see Debian Repository Configuration Format.

To use the enterprise repositories, you need to:

- Install a public GPG key for enterprise repositories
- Configure Qt Account based authentication for enterprise repository access
- Configure repositories

Note: For more details and support,contact us. For more information on free trials, see Qt software free trials.

## Debian Repository Configuration Format

To add extra repositories for APT, insert repositories into a file with an extension of .list under the /etc/apt/sources.list.d directory. For each repository, add a new entry in the file. The generic format is as follows:

     deb [arch=<arch> signed-by=<path>] <REPO_URL> <DIST> <COMPONENT(s)>

An example of an enterprise repository entry:

     $ sudo nano /etc/apt/sources.list.d/tqtc.list

         deb [arch=arm64 signed-by=/etc/apt/keyrings/tqtc/qt-company-debian-repo.gpg] https://debian-packages.qt.io/debian/enterprise/qt-6.10.3-arm64 tqtc-jammy main

See Repository information for Qt Releases for detailed information on how you can configure repositories per Qt release and architecture.

## Debian Source Packages

To add the Debian source packages for APT, you need to add a deb-src entry for the corresponding deb entry:

     $ sudo nano /etc/apt/sources.list.d/tqtc.list

         deb [arch=arm64 signed-by=/etc/apt/keyrings/tqtc/qt-company-debian-repo.gpg] https://debian-packages.qt.io/debian/enterprise/qt-6.10.3-arm64 tqtc-jammy main
         deb-src [signed-by=/etc/apt/keyrings/tqtc/qt-company-debian-repo.gpg] https://debian-packages.qt.io/debian/enterprise/qt-6.10.3-arm64 tqtc-jammy main

To download source packages (for example, for wayland) to the current directory, use the `apt source` command:

     $ sudo apt source qt-6.10.3-wayland-src

## Installing a Public GPG Key

Install a public GPG (GNU Privacy Guard) key for Enterprise Qt Debian repositories as follows:

     $ sudo mkdir -p /etc/apt/keyrings/tqtc  # Create the directory with appropriate permissions
     $ cd /etc/apt/keyrings/tqtc
     $ sudo wget https://cdn.qt.io/debian/keys/qt-company-debian-repo.gpg

## Configuring Authentication

To access the listed repositories, you need an enterprise Qt Account or an evaluation Qt Account.

Note: If your password contains special characters, you may need to escape those by using '\' or '%40'.

Configure the Qt Account credentials for your APT package manager as follows:

     $ sudo nano /etc/apt/auth.conf

           machine https://debian-packages.qt.io
           login <Qt Account login name (email)>
           password <Qt Account password>

Warning: This file may contain sensitive information. To prevent other users on the system from reading the password, make sure the file has strict permissions:

     $ sudo chmod 600 /etc/apt/auth.conf

## Updating Local Package Cache

Update the local package cache as follows:

     $ sudo apt-get update

No errors should originate from the added repository in the output.

## Debian Alias Packages

You can install the content more easily with alias packages, which are just meta-packages pointing to the actual Debian packages.

The contents of the Debian alias packages are listed in the table below.

Note: Qt 6.10.3 release is used in the alias package examples listed below. Always remember to use the packages that match the Qt release you are working on. For more information, see Repository information for Qt Releases.

Alias package name | Package content
--- | ---
qt6.10.3-essentials | essential module libraries essential module runtime tools
qt6.10.3-essentials-dev | essential module libraries essential module headers essential module private headers essential module runtime tools essential module development tools
qt6.10.3-full | essential module libraries essential module runtime tools add-on module libraries add-on module runtime tools
qt6.10.3-full-dev | all module libraries all module headers all module private headers all module runtime tools all module development tools
qt6.10.3-full-dbg | all module debug libraries essential module libraries add-on module libraries

Debian Installation Command Example

     $ sudo apt install qt6.10.3-full-dev

## Full Configuration Example

The following code snippet demonstrates the whole work flow with Enterprise Qt Debian packages:

      # install repository key
      $ sudo mkdir -p /etc/apt/keyrings/tqtc
      $ cd /etc/apt/keyrings/tqtc
      $ sudo wget https://cdn.qt.io/debian/keys/qt-company-debian-repo.gpg

      # configure Qt Account based authentication to Qt Debian repositories
      $ sudo nano /etc/apt/auth.conf
        machine https://debian-packages.qt.io
        login <your Qt Account email>
        password <your Qt Account password>

      # add repositories
      $ sudo nano /etc/apt/sources.list.d/tqtc.list
          deb [arch=arm64 signed-by=/etc/apt/keyrings/tqtc/qt-company-debian-repo.gpg] https://debian-packages.qt.io/debian/enterprise/qt6.10.3-arm64 tqtc-jammy main

      # add source packages
      $ sudo nano /etc/apt/sources.list.d/tqtc.list
          deb-src [signed-by=/etc/apt/keyrings/tqtc/qt-company-debian-repo.gpg] https://debian-packages.qt.io/debian/enterprise/qt-6.10.3-arm64 tqtc-jammy main

      # update local package cache
      $ sudo apt-get update

      # search and install packages
      $ apt-cache search qt6.10.3-full-dev
      ....
      ....
      # files are installed under /opt/qt-6.10.3
     $ sudo apt install qt6.10.3-full-dev

See Repository information for Qt Releases to pick the needed repositories into your /etc/apt/sources.list.d/tqtc.list file.

## Troubleshooting

### Difficulties in authentication

The server may response with the following HTTP error codes:

#### 401 Unauthorized

Wrong credentials. User email and password must be provided in correct format.

Also, try storing the credentials directly into the repository config:

     deb [...] https://<Qt Account email>:<Qt Account passwd>@https://debian-packages.qt.io/.....

If your password contains special characters, you may need to escape those for APT. Use '' or '%40' for escaping those characters or try changing your Qt Account password.

#### 403 Forbidden

Missing credentials.

#### 429 Too Many Requests

User has sent too much failed requests (3 requests per minute).

#### 500 Internal Server Error

Contact Qt support.

### Difficulties with repository GPG key usage

An alternative to the `signed-by` usage attribute in the repository config is to install the key in the following way, although this is not recommended as it's a deprecated way to install it:

     $ sudo apt-key add qt-company-debian-repo.gpg

## Repository information for Qt Releases

Below you can find the Qt releases that the Enterprise Qt Debian packages supports. Pick the needed repositories and add them to your /etc/apt/sources.list.d/tqtc.list as instructed above.

Also, the following tables list the installation directories on your system and the Linux distribution compatible with the packages.

Note: To access the listed repositories, you need an evaluation Qt Account or a commercial Qt Account with a Qt for Device Creation license.

Note: The packages may work on other distributions as well but there is no guarantee on that.
