How should I interpret these KDE5 warnings

After applyying the latest update and rebooting, things appear to be okay… login was good, all my startup apps loaded (Steam, FireFox, Thunderbird, conky, ksystemlog, gufw, and KDE Connect SMS)… however, I have noticed a lot of “metadata complaining” in the logs. Are these safe to ignore or does an action need to be taken?

Note: I just so happened to update my steam beta client prior to installing the manjaro update, and I was able to browse the store and launch a game without issues.

@Daniel-I , you forgot to mention the source of messages and priority level: all of them has priority level of 4 in journalctl, except the kdeconnectd component (I do not have it and do not know).

Plasma spams system journal w/ it’s msgs of priority level 4 for years. It is not critical or even notable (in majority of cases) msgs from Plasma.

What is the priority level of the kdeconnectd messages: do you see the massages with the

$ journalctl -b -p warning | grep "kdeconnectd" | grep "kf.coreaddons: no metadata found in" 

only
or with the

$ journalctl -b -p err | grep "kdeconnectd" | grep "kf.coreaddons: no metadata found in" 

also?

Most useful for investigation of Plasma would be msgs w/ priority level of err (unless you want to investigate the warning level msgs by yourself).

Thank you for the reply @alven

I did take a screenshot which shows an exclamation mark icon… which hopefully helps to indicate the priority…

The first command you shared generated the following:

$ journalctl -b -p warning | grep "kdeconnectd" | grep "kf.coreaddons: no metadata found in" 
Sep 04 14:29:02 AM4-5600X-Linux kdeconnectd[2188]: kf.coreaddons: no metadata found in "/usr/lib/qt/plugins/kf5/kio/desktop.so" "Failed to extract plugin meta data from '/usr/lib/qt/plugins/kf5/kio/desktop.so'"

… the second command you shared didn’t return anything… so I guess that means it was just a warning and not an error?

These messages are warnings, not errors. You shouldn’t bother about it if you don’t want to be KDE developer :wink:

In KSystemLog errors are red, warnings are yellow.

Yes, you can just skip it. Nothing serious and most probably even notable. Plasma spams priority level warning. It is usual.

Also, you entered:

Then asking

Why to guess only? Is it enough or not? Learn if wanna know exactly:

man journalctl

PS
what is that suspicious man? Learn also by calling man of man:

man man

And after that you will know for sure :slight_smile:

ah ha… I see now that the “Select Priorities” dropdown shows a list of the selectable priorities and the colour used to identify each.
