This is just a quick post, I mainly write for myself, in case it should happen to me again. I temporarily broke my Fedora Silverblue installation for the second time by running the command:
sudo rpm-ostree ex livefs --i-like-danger
after I installed a new package.
One has to append
--i-like-danger for a reason, but I didn't want to hear. I wanted to try the new package directly without rebooting my PC.
ex command from
rpm-ostree hides experimental features and
livefs is an experimental feature to apply pending deployment changes to the booted environment.
Here's how I fixed
rpm-ostree crashing on boot with the following error message:
error: Couldn't start daemon: Error setting up sysroot: Parsing deployment 0 in stateroot 'fedora': readlinkat: No such file or directory
With this command you can see the the current boot parameters and find out with deployment is booted:
sudo cat /proc/cmdline
BOOT_IMAGE variable you can see an ID. Now go and see the boot loader entries:
cd /boot/loader/entries ls -la cat ostree-1-fedora.conf cat ostree-2-fedora.conf # you have probably some more deployments
See which of those files doesn't have the ID from above and delete it. In this example it's
sudo rm ostree-1-fedora.conf
Now you can reboot and rpm-ostree should work with no problems.
