Hai, I've uploaded the Debian Buster Samba 4.15.0RC2 packages in the buster-experimental repo. I've also uploaded all the build depends for samba 4.15 to the repo buster-samba415 so if people want to make test builds them self, you have the build depends ready, PLEASE NOTE, there is NO SAMBA in the repo buster-samba415 To get samba 4.15rc you MUST use buster-experimental But at least, all you need is available. Enjoy, If one finds bugs, please report them.. How to use the buster-experimental SETUP : wget -O - http://apt.van-belle.nl/louis-van-belle.gpg-key.asc | apt-key add - echo "# AptVanBelle repo for samba Experimental packages." | sudo tee -a /etc/apt/sources.list.d/van-belle-experimental.list echo "deb http://apt.van-belle.nl/debian buster-experimental main contrib non-free" | sudo tee -a /etc/apt/sources.list.d/van-belle-experimental.list And as normal, apt update && apt install samba winbind Handy to know : apt satisfy samba If your missing packages its pulled in now. ;-) Greetz, Louis
