First, minimal test ISO is uploaded for June stable ISO release

provide the installation log, if you encounter any issue at all

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. Help is especially needed with testing non-free nvidia for the 396 series. So far no such new card is available in the usually used test systems.

There is a bit of an urgency to get a new stable ISO out since it is already longer than usual between releases and the amount of updates since last ISO are far too big.

KaOS ISOs are not only GTK free but are Qt4 & KDE 4 free too.
This is as pure a Qt 5/Plasma 5 ISO as possible.

Plan is to have Frameworks 5.49.0, KDE Applications 18.08.0, Plasma 5.13.4 and Linux 4.17.17 on the final ISO. If all testing goes well expect the final ISO to be released within a week.

Calamares version used is 3.2. Release Notes page is not fully updated yet, you will see some the text from the June 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.

To help with testing:

Use a GPT partition table on BIOS system (manual partitioning)
Use Isowriter to write the test ISO to your USB stick, plan is to remove imagewriter from the repos after this test cycle
Use in live mode on as much different hardware as possible
If you have an UEFI capable system, check if the ISO boots in both UEFI and legacy BIOS mode, make sure though to turn off secure boot
test installs on real hardware are needed, not just vbox
check as many partitioning options as possible in the partitioning of Calamares, see if all works and is clear enough
test with vbox in Live mode and installed and adjust to full screen or resize to different resolutions, this is broken in the last internal test ISOs, it will completely hang the system

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.

The new site for testing ISOs is still in use:

On this ISO you will find:
Linux 4.17.17
systemd 239
gcc 7.3.0
Qt 5.11.1
Frameworks 5.49.0
Plasma 5.13.4
KDE Applications 18.08.0
Calamares 3.2.0
Octopi 0.9.0 with sysinfo & cachecleaner tool

Known issues:

Running the ISO in virtualbox can hang the system at the start of X. It always hangs the system when resizing the screen resolution. This is related to the xorg-server 1.20.1 update. Work is ongoing to debug.
