@kristiandg, for more information you can check the following thread:
There are actually two messages I know you can get when you log on your system too fast, the one you had and the one I described in this post:
Contrary to what I said in the first thread I am referring you to the message you got is not MariaDB (ie database) related (at least not directly if it is) but the reason is the same for both messages, the boot process has not yet finished when you log on.
Have a nice day!
