Help! - 'qt5-default' has no installtion candidate

[Tom Lauzon]

I need some help or direction.  I am constructing a PSWS and have stepped my way through instructions at https://github.com/HamSCI/PSWS_Documentation/wiki/HF-wsprdaemon-Receiver.

I have gotten to the point where I am done with changes to the configuration file and have typed "./wsprdaemon.sh -V".  Things run for a few second and then I get the message 'qt5-default' has no installtion candidate.  After which everything stops.

Is there something I am missing?  I am not very good at Linux at this point and would appreciate any guidance.

Thank you.

Hello Tom,

I did a search on the error message you reported and got the following result:

The error 'qt5-default' has no installation candidate occurs because the qt5-default package was removed from the official repositories of newer Linux distributions, such as Ubuntu 21.04+, Debian 11+, and recent Raspberry Pi OS versions. [1, 2, 3]

To resolve this, you must install the individual components that were previously bundled in qt5-default. [1, 2]

Recommended Solution

Run the following command to install the necessary development libraries and tools: [1]

bash

sudo apt update
sudo apt install qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools

Use code with caution.

[1, 2, 3]

Why this happened

• Package Obsolescence: Distro maintainers replaced the single "default" package with more modular options to give developers better control over their environment.
• Transition to Qt 6: Many systems are shifting toward Qt 6, leading to the phasing out of older Qt 5 convenience packages. [1, 2, 3, 4, 5]

Common Additional Packages

Depending on your project, you might also need these specific modules:

• For UI development (PyQt5): sudo apt install python3-pyqt5.
• For Qt Creator IDE: sudo apt install qtcreator.
• For Graphics/SVG support: sudo apt install libqt5svg5-dev. [1, 2, 3, 4]

If you are following an older tutorial, simply replace the qt5-default part of their install command with qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools

Hopefully this will help you resolve the problem.

With the help of the community, I have made significant progress on getting my PSWS up.  I have gotten as far at connecting the RX888 and the GPS reference.  Now I am encountering the error message that onion/log.h does not exist.  There appears to be an onion sub-directory and an onion-build.log, but log.h is missing.  If someone could tell me where to create this and what to put in it, I would appreciate it.

Thanks in advance,

Tom Lauzon
