Configuration file "var/lib/sddm/.config/sddm-greeterrc" not writable. Please contact your system administrator

I get this message on the Lenovo boot screen. I have to click “OK” and then the system boots normally. I don’t know what caused it, what it is related to and how to solve it. Thank you very much in advance.

Hi @ivangouba, and welcome!

I thought this means the runtime configuration (?) file’s permissions are incorrect. But, I couldn’t find that file. So it led me to Google a bit, leading me to this page where one of the answers is:

Got the same issue on my install.

Just touch the file at that address:

touch /var/lib/sddm/.config/sddm-greeterrc

So go ahead. and try that.

Hope it helps!
