\brief Instructions How to Use Enterprise Qt Debian Packages.
\title Enterprise Qt Debian Packages
To use Enterprise Debian packages with Qt, add your enterprise repositories to Advanced
Packaging Tool (APT). For details, see
\l{Debian Repository Configuration Format}.
To use the enterprise repositories, you need to:
\list
\li \l{Installing a Public GPG Key}{Install a public GPG key} for enterprise repositories
\li \l{Configuring Authentication}
{Configure Qt Account based authentication} for enterprise repository
access
\li \l{Full Configuration Example}{Configure repositories}
\endlist
\section1 Debian Repository Configuration Format
To add extra repositories for APT, insert repositories into a file with an
extension of \e{.list} under the \e{/etc/apt/sources.list.d} directory. For
each repository, add a new entry in the file. The generic format is as
follows:
\badcode
deb [arch=<arch> signed-by=<path>] <REPO_URL> <DIST> <COMPONENT(s)>
\endcode
An example of an enterprise repository entry:
\badcode \QtVersion
$ 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-\1-arm64 tqtc-jammy main
\endcode
See \l{Repository information for Qt Releases} for detailed information
on how you can configure repositories per Qt release and architecture.
\section1 Debian Source Packages
To add the Debian source packages for APT, you need to add a \e {deb-src}
entry for the corresponding \e {deb} entry:
\badcode \QtVersion
$ 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-\1-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-\1-arm64 tqtc-jammy main
\endcode
To download source packages (for example, for \e wayland) to the
current directory, use the \c {apt source} command:
\badcode \QtVersion
$ sudo apt source qt-\1-wayland-src
\endcode
\section1 Installing a Public GPG Key
Install a public GPG (GNU Privacy Guard) key for Enterprise Qt Debian
repositories as follows:
\badcode
$ sudo mkdir -p /etc/apt/keyrings/tqtc # Create the directory with appropriate permissions
$ cd /etc/apt/keyrings/tqtc
\endcode
\section1 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 \b'\\' or \b'%40'.
Configure the Qt Account credentials for your APT package manager as follows:
\badcode
$ sudo nano /etc/apt/auth.conf
login <Qt Account login name (email)>
password <Qt Account password>
\endcode
\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:
\badcode
$ sudo chmod 600 /etc/apt/auth.conf
\endcode
\section1 Updating Local Package Cache
Update the local package cache as follows:
\badcode
$ sudo apt-get update
\endcode
No errors should originate from the added repository in the output.
\section1 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 \QtVersion 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 \l {Repository information for Qt Releases}.
\table
\header
\li Alias package name
\li Package content
\row
\li qt\QtVersion-essentials
\li
\list
\li \l {Qt Essentials} {essential module libraries}
\li essential module runtime tools
\endlist

\li qt\QtVersion-essentials-dev
\li

\li \l {Qt Essentials} {essential module libraries}
\li essential module headers
\li essential module private headers

\endlist
\endlist
\endtable
\b {Debian Installation Command Example}
\badcode \QtVersion
$ sudo apt install qt\1-full-dev
\endcode
\section1 Full Configuration Example
The following code snippet demonstrates the whole work flow with
Enterprise Qt Debian packages:
\badcode \QtVersion
# install repository key
$ sudo mkdir -p /etc/apt/keyrings/tqtc
$ cd /etc/apt/keyrings/tqtc
# configure Qt Account based authentication to Qt Debian repositories
$ sudo nano /etc/apt/auth.conf
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/qt\1-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-\1-arm64 tqtc-jammy main
# update local package cache
$ sudo apt-get update
# search and install packages
$ apt-cache search qt\1-full-dev
....
....
# files are installed under /opt/qt-\1
$ sudo apt install qt\1-full-dev
\endcode
See \l{Repository information for Qt Releases} to pick the needed
repositories into your \e{/etc/apt/sources.list.d/tqtc.list} file.
\section1 Troubleshooting
\section2 Difficulties in authentication
The server may response with the following HTTP error codes:
\section3 401 Unauthorized
Wrong credentials. User email and password must be provided in correct format.
Also, try storing the credentials directly into the repository config:
\badcode
\endcode
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.
\section3 403 Forbidden
Missing credentials.
\section3 429 Too Many Requests
User has sent too much \b{failed} requests (3 requests per minute).
\section3 500 Internal Server Error
\section2 Difficulties with repository GPG key usage
An alternative to the \c {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:
\badcode
$ sudo apt-key add qt-company-debian-repo.gpg
\endcode
\section1 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
\e{/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.
