Obviously, the June release was delayed, so starting a new topic for a July release. Early on it wasn't clear if linux 5.7 was usable or not as the next stable kernel, but things seems to have settled now that it is at 5.7.7.

Also not clear was how many of the new Calamares QML modules were ready for ISO use, it now looks like welcomeq & keyboardq can be used, localeq is not ready

As always, early test ISOs are minimal, very few apps, just a web-browser, file manager, text editor, GUI package manager. The non-free nvidia drivers are included since they are a big part of what needs testing.

Plan is to have Frameworks 5.72.0, KDE Applications 20.4.3, Plasma 5.19.3 and Linux 5.7.x on the final ISO.

The ISO is using packages from the build repo, but that repo is not enabled, so if you decide to install, make sure to add the build epo to your pacman.conf.

Debug packages for Calamares are part of all ISOs, run Calamares with gdb if you encounter errors.
provide the installation log, if you encounter any issue at all

You can start Calamares from the Welcome app, or run it with:

sudo calamares -d

The install log will be created in the home directory of the Live user, see ~/installation.log. It is available after the install in the target system in /var/log/installation.log
If run from cli, make sure to pastebin the full output, since no installation.log will be copied then, though that log is more complete.

Known issues:

Virtualbox in VMSVGA graphical mode will not scale the guest display. Either run in (older) VBoxSVGA or as root (sudo will not work, actually use su to become root): /usr/bin/VBoxClient --vmsvga, seems fixed in Live mode, not yet on installed system
