My thinkpad E520 runs fedora 27. When I boot the OS, I cannot login into the UI. But after the splash screen i get a list of Errors, where It sais “Failed to Start Process Core Dump” after several processes It tried to start. I took a picture:
I still can login with a console via ctrl+alt+f2
Unfortunately, you are running a version of Fedora that went end-of-life back in 2018. I strongly recommend that you backup your machine and reinstall Fedora 36 on it, especially as it is meant to be a network connected machine as you’re attempting to run sssd on it. I suggest reporting back once you are on a currently supported version of Fedora.
The login problems are more likely to be due to the sssd service failing to start. The systemd-coredump service stuff might be a red herring here. I don’t suppose you have a local admin account aside from sssd that might help you get to the logs to figure out why sssd is failing (journalctl --boot -u sssd)? It’s possible that you are on a network that can’t access the directory server?
I propose to login with a live ISO and make a backup of your data you really need. With Fedora27 you are way back behind (almost 10 Versions).
It is probably a good idea to make a new install. With the live ISO you can also check if your Laptop is still working as it should.
Try to do that what @vwbusguy proposed while login with a console.
I used a live usb stick and installed the newest fedora. During installation I had a new problem, which I describe here.
A thinkpad and IoT?
IoT is one of the immutable spins and I would strongly suggest you try with the workstation install instead to see if the error is a result of the particular spin or hardware related.
I suspect that the problem is related to btrfs and that the subvolume mounted at / is named root so it somehow gets put into the initramfs that way and causes the error.
