Unknown Error Code 100

I have had this issue with different programs with them all coming from "Error - Plasma" and from "Error - KIOExec" Both referencing a "Unknown error code 100". I'll give a few examples.

With creating a .py file and setting it as an executable, I get specifically;

Unknown error code 100
execvp: Exec format error
Please send a full bug report at https://bugs.kde.org.

With downloading "Mod Organizer 2" from Lutris, I get;

Unknown error code 100
Could not find the program 'modorganizer2-nxm-broker.sh'
Please send a full bug report at https://bugs.kde.org.

What should I do about fixing these errors? What am I missing?

We are not KDE :wink:

Welcome to Garuda Linux Forum :slight_smile:

echo -e {$PATH\n}
find -iname '*modorganizer2-nxm-broker.sh*'  <-- or something like that, check if executable

Did you reboot after your last update?



Yes, I have.

Just thought I'd check as many times this is forgotten by users new to a rolling distro.


Had Garuda for about a month now. Ever since I tried to create a Python file, thought I should check this in since I got the same error code more than once.

Try to post the bug to KDE.

I cant help about, sorry.

Will do, just thought I should ask, but thanks.

One question though. Which product should I enter as a bug? Should it be the lattedock since the version of Garuda I use uses that? Which is it for the error the Python file made?

Oh, I thought it is a python problem.

I have no problems with latte-dock may be the developer @psifidotos can help?

The problem is something about executables and I've had the problem a few times ever since beginning Garuda. I just don't know where in this "Pick a product on which to enter a bug" in bugs.kde.org I should address it to?

It seems the qt5-base is broken, or as far as I read. How would I go about downgrading it to make it work as it should or is there a way I can download something else to fix it?

Info gotten from: Qt5-base 5.15.2+kde+r203-1 severely breaks .desktop files - #17 by UltraBlack
and 439185 – qt5-base breaks desktop files

Lets bump +1

We don't do that here. It is considered rude behavior.


So, am I supposed to let it die after a 2 day time period without an answer? I'm now looking for a way to downgrade the qt5-base.

If you have been continuing troubleshooting efforts, then keep very detailed records of everything you have tested as well as any related search information you have uncovered. If no one has posted any further advice regarding your issue, then post the detailed list of troubleshooting procedures you have recently performed. Also post any new info you have uncovered online since your last post, (be sure to post links).

This demonstrates that you are being proactive by continuing to research and troubleshoot on your own (even if others aren't currently offering suggestions). Posting a detailed synopsis shows forum helpers that you are motivated and are attempting to work through your issues yourself. This goes a long ways to getting some good will towards yourself, as this shows initiative. This is actually a very important factor, because helpers on the forum are far more likely to respond to users who demonstrate they are not lazy and don't require being spoon fed every answer.

Most forum helpers find empty bumps a turn off. Empty bumps mostly tend to just get you a bad reputation and even less assistance on the forum. Our forum does not look favorably upon empty bumps and they are strongly discouraged.


Alright, I understand. Then here's an update. Updating the qt5-base to the version that was released today did not fix anything. Planning to downgrade to
from Index of /packages/q/qt5-base/ and all other qt5 packages to match versions of the qt5_base now that I have.
P.S. I should also add I am following the guide from How to Downgrade a Package in Arch Linux (Manjaro) - YouTube

Reverted and... that did not work. @UltraBlack, What versions did you downgrade to when you rolled back and was there anything else?

You updated the entire system, right, not just qt5-base? You're familiar with partial update scenarios?


Yes, I did as I updated the entire system from the "add/remove software, and double checked with sudo Pacman -Syu and then restarted, Although I am not familiar with partial update scenarios. When I tried to both start a created python file and tried the same issue with mod organizer 2, both still had the same problems they had before.
