> ​Nick, that's perfect, thanks. I'll try to re-upload my earlier kdb.git and kexi.git stuff. I believe the red errors I reported earlier may be not technical but because of permissions. Let's see.

but if you upload to KDE account, then please build all other kde stuff (it takes 15 hours on my laptop with ssd), otherwise all found issues for other projects will disappear
