[issue]: Compile GUI for Qt6 & Upgrade CI base image

[Technetium1]

Official FAQ

• I have checked the official FAQ.

Ventoy Version

1.0.98

What about latest release

Yes. I have tried the latest release, but the bug still exist.

What happened?

The current AUR package correctly states that the target is Qt5. This should not be the case because Qt6 seems to be properly supported! When looking at https://github.com/ventoy/Ventoy/blob/master/LinuxGUI/Ventoy2Disk/QT/Ventoy2Disk.pro and seeing

Ventoy/LinuxGUI/Ventoy2Disk/QT/build/Makefile

Line 3 in 0ffb1b1

# Generated by qmake (3.1) (Qt 5.9.0)

generated as a result, it shows that it's long past the time for change:

• https://code.qt.io/cgit/qt/qtbase.git/commit/?h=5.11
• https://endoflife.date/qt (expand to see 5.9)

This image being used for builds is no longer acceptable: https://hub.docker.com/_/centos

"This image is no longer supported/maintained (non-EOL tags last updated November 16, 2020)"

This should be an extremely high priority issue.
