linuxfoundation yocto DOWNGRADE

Affected: 2.6 · 3.3 · 4.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.6

1. Check installed version

apt-cache policy yocto || rpm -q yocto || yocto --version

2. No fixed release: DOWNGRADE to a release before 2.6 (Debian / Ubuntu)

apt-cache madison yocto sudo apt install yocto=<VERSION_BEFORE_2.6> sudo apt-mark hold yocto
