Also your tags say rqt but the error is for qt-build.

This seems like a problem with infrastructure, not with Qt itself, or the qt_build package @osilva.

@ishaniis: the URL shown in the error is valid, and I can download the file it points to.

This might have been a transient error, or something local to your connection / organisation.

Does it keep happening? Is it just that package, or other packages as well?

Are you behind a (corporate) firewall or proxy?

@gvdhoorn

Q: Does it keep happening? A: I've got this error for the first time.

Q: Is it just that package, or other packages as well? A: It's just happening with this package. I am not sure but I got the same error during rosdep too! (but not sure though)

Q: Are you behind a (corporate) firewall or proxy? A: Yup.

@gvdhoorn so I've purged one of package and tried to reinstall, to check for installation with the normal package, like vim and It was installed like a charm! Not sure, why its happening with this package itself.

It could be the proxy or firewall is somehow blocking this package. I've seen stranger things. URL filtering rules may be interfering.

If other ROS packages do work, it might be this is something you'll have to find a work-around for.

To make sure it isn't a cache issue, you could try sudo apt clean && sudo apt update and try installing again.

But no guarantees.
