1journalctl -k shows dmesg (kernel messages), you can get the same output by simple running the command "dmesg". To check if journalctl is working for non-kernel messages just type journalctl -b, if that doesn't give any logs then paste the output of systemctl status systemd-journald*Hesham Ahmed– Hesham Ahmed2016-06-07 21:54:39 +00:00Commented Jun 7, 2016 at 21:54

1You could also get this error message, if you query logs for a specific service, and just made a typo in the service name, as I just did.bvdb– bvdb2019-04-19 16:21:06 +00:00Commented Apr 19, 2019 at 16:21

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
