I'm on Ubuntu 18.04.1 LTS x64 and I need to update my Qt 5 installation from v5.9.5 to v5.10.0, however when I issue the command

sudo apt-get install qt5-default

it gives me that

qt5-default is already at the latest versione (5.9.5+dfsg-0ubuntu1).

But obviously it's not true.
I've also tried running:

sudo apt-get update

sudo apt upgrade

sudo apt dist-upgrade

before, but without success.

What is wrong with those commands? I just need to install the core libs without the UI stuff (e.g. qtcreator).

I spent several weeks messing with a system level replacement of Qt 5.9.5 on Ubuntu Bionic and it didn't seem feasible without a backport. The qtxxx.run file will install to /opt which is correct but ancillary and would require some environment variable and/or path override. I built some programs against qt in /opt but they didn't work well just because everything wants to use system default.

System Qt is distributed in a wide array of folders that exist in parallel where the /opt is in a tree. This magic appears to happen toward the end of the debuild/backportpackage type process where the rules makes changes to some of the paths stored in files to mesh with Ubuntu's structure. I was unable to backport upstream versions because of chicken and the egg situations where cross-package dependencies fail even with the bootstrapped qmake.

Long story short, at least for me, best to stick with the Qt version that's part of the distro. It is a core item that isn't meant to be either replaced or have multiple versions without very careful testing.

This was my experience but that doesn't mean it's fact. I'd be pleased to hear if anyone had more success.
