\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 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{Repository Configuration Example}{Configure repositories}
\endlist
\note The Enterprise Qt Debian packages are provided as technology-preview
packages. For more details and support,
\l{https://www.qt.io/contact-us}{contact us}.
\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
$ sudo nano /etc/apt/sources.list.d/tqtc.list
deb [arch=arm64 signed-by=/home/<user>/keyrings/tqtc/qt-company-debian-repo.gpg] https://debian-packages.qt.io/debian/enterprise/qt-6.3.1-arm64 tqtc-focal main
\endcode
See \l{Repository information for Qt Releases} for detailed information
on how you can configure repositories per Qt release and architecture.
\section1 Installing Public GPG Key
Install a public GPG (GNU Privacy Guard) key for Enterprise Qt Debian
repositories as follows:
\badcode
$ mkdir -p $HOME/keyrings/tqtc # pick a suitable location for you!
$ cd $HOME/keyrings/tqtc
$ wget https://cdn.qt.io/debian/keys/qt-company-debian-repo.gpg
\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
machine https://debian-packages.qt.io
login <Qt Account login name (email)>
password <Qt Account password>
\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 Full Configuration Example
The following code snippet demonstrates the whole work flow with
Enterprise Qt Debian packages:
\badcode
# install repository key
$ mkdir -p $HOME/keyrings/tqtc
$ cd $HOME/keyrings/tqtc
$ 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=/home/<user>/keyrings/tqtc/qt-company-debian-repo.gpg]
https://debian-packages.qt.io/debian/enterprise/qt-6.3.1-arm64 tqtc-focal main
# update local package cache
$ sudo apt-get update
# search and install packages
$ apt-cache search qt6.3.1
....
....
# files are installed under /opt/qt-6.3.1/
$ sudo apt-get install qt6.3.1-declarative-dev qt6.3.1-declarative-private-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
deb [...] https://<Qt Account email>:<Qt Account passwd>@https://debian-packages.qt.io/.....
\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
Contact \l{https://www.qt.io/contact-us}{Qt support}.
\section2 Difficulties with repository GPG key usage
An alternative to 'signed-by' usage attribute in the repository config is to
install the key in the following way, althoug this is not recommended as
it's 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 used to build the packages.
