After doing a timeshift I am completely unable to sign into my machine, I enter the right info but it signs me out and takes me back to the login right after, i tried logging in using the tty line and the same issue occurs. Please help.
Try logging as root.
What did you restore in the timeshift and from how long ago?
I restored from 1 day ago when everything was fine, and i can’t seem to log into root either, but when i log in as my user something pops up very briefly but i cant read it as it disappears far too quickly
What did you select to backup in timeshift?
Also, what happens when you try to log in as root from the TTY?
I did a standard timeshift rsync restore. and i cannot log into the root at all, it says my password is wrong, and when i log into my user it says " – [username]: no shell: Permission Denied"
Could it be an issue related to selinux?
You can try to edit the grub entry:
Hold the shift key down when you power on. The GRUB menu should appear.
Press “e” to edit the entry.
Add enforcing=0 at the end of the linux line.
Now press “Ctrl+x” to continue the boot process.
If you can log in, you have to relabel the filesystem. If the issue is still here, my assumption was wrong 
and it isn’t an selinux issue.
I caved and just reinstalled after copying all my important files in the live usb environment, i realized without root access to the system there wasn’t much i could do.
Hi! sry for the late reply, i’m having the same issue and now I can login thks to adding enforcing=0. Now what’s next? I really aprecciate any guidance on how to do a correct timeshift
Yes, this is a post a bit old.
Btw, now, try with
sudo touch /.autorelabel
then reboot without such grub option.

Thank you so much, and sorry for reviving an old post.
The method you suggested was actually the simplest and most accurate solution for my issue. I ran the command and rebooted, but at first, nothing happened. Then I rebooted again and re-added the enforcing=0 lines — and that seemed to start repairing the error.
Now everything is working again — I really appreciate your help!
Just one last thing: do you have any suggestions on how to make a better Timeshift setup next time? And if possible, do you know what might have caused this issue in the first place?
