Downloaded, checksumed and flashed following ISO’s twice:
And used the Architect installer to install Manjaro KDE Plasma full or minimal unstable branch with systemd-boot. But the installation ended always with package download errors. Don’t know if it were always the same packages that failed during my various install attempts. But I have noted the following package messages once:
Kjobwidgets-git -> The reported URL returned error: 404
Kdbusaddons-git -> The reported URL returned error: 404
Kcrash-git -> The reported URL returned error: 404
Kguiaddons-git -> The reported URL returned error: 404
Ktextwidgets-git -> The reported URL returned error: 404
These error messages lead to the final message that did abort the installation:
Error: [install basepkgs]
Tried also different mirror servers with no luck. A single mirror server doesn’t help either. Tried mainly servers in Germany (i.a. Manjaro servers), Netherland and Denmark.
But then I switched to the stable branch and the installation went smooth to the end without any problem.
So I suspect that the Architect KDE unstable branch installation might be broken on both tested ISOs.
