It occurred after a dnf upgrade from Fedora 29 to Fedora 30 Version-Release number of selected component (if applicable): How reproducible: The reproducibility was described in Bug 1492208 - it involves the removal of the os-release file from /usr/lib, which is symlinked to /etc/ Steps to Reproduce: Described in Bug 1492208 Additional info: The result after upgrading from Fedora 29 to Fedora 30 was a boot that failed with the Failed to switch root: Specified switch root path /sysroot does not seem to be an OS tree. os-release file is missing. I had to reboot of live distro (Clonezilla) Activate the LVM and mount the root volume Copy a copy of os-release from another working fedora 30 installation into mounted root's volume /usr/lib I had problems generating a valid symlink so copied the os-release file to the mounted root's volume /etc/ directory Successfully rebooted the installation.
I was able to fix this without having to reboot with alive distro or go through the hassle of mounting an LVM (whose multiple steps I never remember). It's in comment in https://bugzilla.redhat.com/show_bug.cgi?id=1705651.
