Installation Error

[patrickm]

I am trying to install Qt Creator on Ubuntu 1804 and I am getting this error:

Error during installation process (qt.qt6.630.gcc_64):
Could not find the required QmakeOutputInstallerKey(qt.qt6.630.gcc_64_qmakeoutput) value on the installer object. The ConsumeOutput operation on the valid qmake needs to be called first.

This same question/error message was reported very recently on this forum, you might search to find it.

I don't know for sure how relevant it is for Qt Creator, and that particular error message, but given https://bugreports.qt.io/browse/QTBUG-89388

Ubuntu 18.04 isn't supported development host for Qt6,

how far do you expect to get with Qt6 anyway?

@JonB Thanks I'll try installing on 20.04

@finch Hi and welcome to devnet,

Based on the 6.7 supported platform list, you need Ubuntu 22.04.

I am getting a similar error. I am using WSL Ubuntu 24.04 with GCC 13.3.0

@NathanJS

hi, i think it could be related to qmake.

@NathanJS What exactly are you installing and how?

Hi, I am installing QT 6.8.2 using the Linux x64 Online Installer.

• I downloaded the file qt-online-installer-linux-x64-4.8.1.run from here

• Then did chmod +x qt-online-installer-linux-x64-4.8.1.run

• Finally ./qt-online-installer-linux-x64-4.8.1.run

This is the message I am getting:

error during installation process (qt.qt6.681.linux_gcc_64): could not find the required qmakeoutputinstallerkey(qt.qt6.681.linux_gcc_64_qmakeoutput) value on the installer object. the consumeoutput operation on the valid qmake needs to be called first.

I fixed the issue by running sudo ./qt-online-installer-linux-x64-4.8.1.run instead of ./qt-online-installer-linux-x64-4.8.1.run

I performed exactly the same procedure and encountered the same problem, but even running the command with "sudo" does not change anything.

Debian 12 on wsl2 with gcc 12.2.0
