RC1 for KiCad 5.0.0 is available since few days.
A dedicated PPA (for Ubuntu) is now available for this branch. It’s available at:
This PPA will follow all 5.0 releases.
To use it:
sudo add-apt-repository ppa:js-reynaud/kicad-5 sudo apt-get update sudo apt install kicad
If you are using daily build AND want to stay in 5.0:
You must remove daily build ppa from your sources and remove any existing kicad packages before installing any 5.0 version.
Keep in mind that daily build package will be always more recent than any release packages.
Enjoy testing !
