How to Update Qt 5.4.1 to Qt 5.5?

Question

I want to update qt 5.4.1 to Qt 5.5 or 5.4.2 because I want to test KDE Plasma on WayLand.

Note: Please provide solution that consume least network resources as I have limited bandwidth. KUbuntu 15.04

Solution 1

I advise you to install a virtual machine and install Ubuntu 15.10 indide this environment. Wily includes Qt 5.4.2.

Do not try to update your Vivid system with Qt 5.4.2.

Solution 2

As mentioned in other answers, this is not really recommended and may cause issues, however, if you really want it, go HERE and download the .run installer or

wget download.qt.io/official_releases/online_installers/qt-unified-linux-x64-online.run

chmod +x qt-unified-linux-x64-online.run

~/qt-unified-linux-x64-online.run

This will start the qt 5x installer.

Solution 3

Short: not ready yet.

Just curious, what are the reasons to update? Is it segfaulting on every connect/disconnect of an external display? bugs.kde.org/show_bug.cgi?id=341497

I decide not to give it try as it is around 800MBs. Second, I replied after many days because my laptop bios get corrupted and I fixed it. Thank you everyone. Hope to test it when 15.10 released.
