Qt6.5.5 in Ubuntu 24.04 Container

DK999

Hi guys!
Trying to install Qt 6.5.5 in a docker container to make it easier for our devs to have a consistent work environment.
But I'm encountering a weird error message I don't really understand, since installing it with the same command inside a running container works perfectly fine.

I'm installing it like this inside my dockerfile, which looks fine to me

COPY qt-enterprise-linux-x64-6.5.5.run /home/ubuntu/qt-enterprise-linux-x64-6.5.5.run
RUN install -d -m 0755 -o ubuntu -g ubuntu /home/ubuntu/.local/share/Qt
RUN install -d -m 0755 -o ubuntu -g ubuntu /home/ubuntu/.local/share/icons
COPY qtaccount.ini /home/ubuntu/.local/share/Qt/qtaccount.ini
RUN chown ubuntu:ubuntu -R /home/ubuntu
USER ubuntu
RUN chmod +x /home/ubuntu/qt-enterprise-linux-x64-6.5.5.run

RUN /home/ubuntu/qt-enterprise-linux-x64-6.5.5.run --root ~/qt6.5.5 --accept-licenses --default-answer --confirm-command install qt.qt6.655.gcc_64

Version of Qt doesn't matter, have the exact same issue with current 6.7.1.
Any ideas what I'm missing?

Hi and welcome to devnet,

Not a direct answer but did you consider using the aqtinstall project to handle the installation part ?

Not yet, since I don't know if I can use it with our pro licenses or if it just installs the open source variants.
Can someone tell me where the difference is between the two install types? Can I switch from Open Source to license that easily?

EDIT:
When I install qmake6-bin via apt-get install qmake6 it works just fine, why does the installer need a qmake version from my system instead of using the one it's installing?
Do I need to add the path to the qmake to my $PATH upfront?

If anyone struggles with this - build from source....

@DK999, I am having almost exactly the same problem that you describe here, and have created a new forum topic post for it at: https://forum.qt.io/topic/157337/error-installing-qt-6-5-5-into-ubuntu-22-04-docker-container. You said here that when you installed qmake6-bin via "apt-get install qmake6" that it solved the problem for you, but I tried adding that to my dockerfile and it had no affect. Do you have any other advice?
