QTMaintenanceTool fails installing on Ubuntu 20.04lts due to qtlicd compiled with glibc version > 2.31

[ccamporesi]

While installing the new QtCreator 13.0.0 enterprise on a Ubuntu 20.04lts, the MaintenanceTool fails due to qtlibc compiled with an incompatible version of GLibC.
GLibC deployed in Ubuntu 20..04 LTS is Glibc 2.31 and qlicd requires 2.32+. QtCreator and Qt 6.7.0 are still compatible.
Can this problem be corrected or should we assume that Ubuntu 20.04 LTS will not be supported?
If so, is qtlicd a mandatory process for QtCreator 13 enterprise license mgmt or can we skip the installation of it?
Thank you and have a great day,
Carlo

Hi and welcome to devnet,

Based on the documentation's list of supported platforms, the current minimal Ubuntu version is 22.04.

Since you seem to have a commercial licence, you can try discussing this matter with the Qt Company directly.

@SGaist thank you for the prompt answer. I saw the platform specs for the library as well but I could not find the the minimum requirements listed anywhere for QtCreator.
It seems that the installer does not really care which OS you are working on and it keeps suggesting to upgrade even though the OS is not supported.
Maybe a good use case for a feature request.
Have a great day.

@ccamporesi for Qt Creator, it will depend on the version of Qt used to build it.

Note that this does not influence which version of Qt you use to build your application.

@ccamporesi definitely, I understand that. Thank you
