SELinux prevents me from login in since installation

pedrofleck · 11-17-2018, 07:26 AM

I just installed Fedora 29 and I couldn't make it boot (a lot of things failed, like NetworkManager and GDM), I reinstalled numerous times with different settings and then I tried booting with GRUB command "selinux=0" and it worked. Then I reboot and tried to boot with SELinux enabled again: now I can't login, not in GDM neither in command line. Setting it to permissive doesn't work either. What can I do?

Your installation seems to have gone wrong. I would reinstall.

I reinstalled numerous times and checked the media before.

There might be files with the wrong SEL labeling. Have a look here
https://docs.fedoraproject.org/en-US...g_SELinux.html
and try the instructions for enabling. Of course, you could just run Fedora without SEL, as many people do. After all, Red Hat & Fedora are the only distros that enable it and no-one else suffers dire consequences as a result!

Yeah, I relabelled as explained there, but then I got the problem that my system won't boot like the first time (errors: https://i.imgur.com/uCyI7dY.jpg). I'm running without it, however, it's a system breaker problem that can affect someone that won't know that is caused by SEL or how to fix it.
