Do you use Ubuntu resources only?
AFAIK you can use the linux maintenance tool for downloading any version of Qt from https://www.qt.io/download

If you are 32-bit you should not be running a 64-bit installer.

You can see from https://askubuntu.com/a/1117540/475088 how someone else did it, substitute correctly for the version of Qt you want and the correct architecture.

@sharath At some point Qt Company stopped to provide 32bit Qt builds, but I think it was after Qt 5.5, so I would guess that there should be something newer than 5.5.
Anyway, do you really have to use 32bit OS?
