Well, I want a notes-programm and for that I installed kjots. But after installation it doesn't start. I don't know where to search or whre I can find logs for this programstart. Can anybody help me? KaOs is up-to-date.

Works here. Make sure you have akonadi and kdepim (maybe it has missing deps)

sudo pacman -S akonadi kdepim

No need for kdepim, works here with existing deps (minimal install, no kdepim).

Make sure to post the error when trying to run, start form cli with "kjots" and post the full result here from that command until it crashes.

Ok, when I start from cli, kjots starts.
This is what cli says:

But when I try to start Kjots from the K-Menu, it ends whitout starting

OK, this is one of the common upstream .desktop file issues.
Until this is fixed upstream you can do a quick workaround/fix locally:

kdesu kate /usr/share/applications/org.kde.kjots.desktop

Look for the line

Exec=kjots -caption %c

and remove -caption %c
save, now it will start from the menu too.

EDIT:
A patch is available
https://github.com/KDE/kjots/commit/d536dbdf606d18baa437d03a9852fa6bb7289953
Rebuild kjots with this patch will be up shortly.

Also, Zanshin is a "getting things done" software quite similar tor KJots. Give it a try if you're looking for a notes-programm.
Other options in the repos are Papyrus, Basket and Qtnote.

After the update today Kjots starts perfectly.... Thanks demm 🙂

@adurol
Thanks for your suggestions. I will give them a try 🙂.
