Unable to create io-slave: klauncher said: Error loading 'kio_file'.

I am getting this:

Could not start process Unable to create io-slave:

 klauncher said: Error loading '/usr/lib64/qt5/plugins/kf5/kio/file.so

from trying to run a font install from within Font Management-System Settings but it also comes up on other occasions (sometimes in Yast)

I have seen suggesting running zypper dup but is that for Leap too? If I do invoke this from within the terminal I get a massive list of files to upgrade/downgrade/new etc etc.

I have the following repos:

Does this also occur on a fresh user account?

Does the file exist?

Try to reinstall kio-core:

sudo zypper in -f kio-core

Try to run “kbuildsycoca5 --no-incremental” as user.

If that doesn’t help:
Run the corresponding application in a terminal window and see whether you get some output.
And post the output of:

ldd /usr/lib64/qt5/plugins/kf5/kio/file.so

but it also comes up on other occasions (sometimes in Yast)

I don’t see why it should come up in YaST. YaST is no KDE application.

I have seen suggesting running zypper dup but is that for Leap too? If I do invoke this from within the terminal I get a massive list of files to upgrade/downgrade/new etc etc.

Normally you should only run “zypper dup” to upgrade to a different distribution version.

But it can also be used to bring back your system to a consistent state if you messed it up by adding additional repos. E.g. remove all repos except the standard ones, and a “zypper dup” will (hopefully) put your system back to the Standard release.

Unfortunately the layout of your posted repo list is completely messed up, so it’s hard to give specific advice.
You should use [noparse]

tags, not [QUOTE] tags[/noparse] for such output.

Thanks. Before we get into the rest of this are there any repos on this list I should delete?

Reinstalled the file and didn’t help.

The repos in your list should not cause such a problem, I think.

Yeah, especially without line feeds… :wink:

But it looks like all necessary libraries are found.

Hi,

I am trying to use plasma today and saw this error when I launch some application.
I was able to solve it by right clicking the k menu button and in edit application
under edit click the restore to system menu.

#6

Well, this will remove all personal customizations to the menu, and might help if you created invalid menu entries or otherwise messed up the menu.

But TBH, I don’t see how it should help here with this particular error…

#7

I hear you, this could happen probably when you fresh install leaving the /home directory untouched.
without cleaning which happened here during the installation of leap.
This machine here in question used to have a kde4X prior to installation of leap though was occasionally
use because xfce is being used as the main os. With the new leap installation nothing was customized inside
plasma.

#8

I have this same problem with kio plugin for baloo. So much, that I can’t use Dolphin at all, and I had to go back to using Konqueror instead.

For the record, these plugins fail:

/usr/lib64/qt5/plugins/kf5/kio/timeline.so
/usr/lib64/qt5/plugins/kf5/kio/trash.so
/usr/lib64/qt5/plugins/kf5/kio/file.so

I checked versions, they are all 5.15.0, up-to-date. Dolphin is 15.08.2.

#9

Does it work in a fresh user account?

How do you start dolphin?
Try running it in Konsole and see whether you get more detailed output.

Maybe you have old KDE4 menu entries left that cause this?
Try to remove/rename ~/.local/share/applications/.
Or maybe you are using launcher icons from KDE4 in your Desktop folder?

#10

Dolphin is version 15.08, I started it from krunner and from terminal. Here is more output.

Hm, doesn’t tell much more either, unfortunately.

What versions of kio, kio-extras5, and baloo5-kioslaves do you have installed?

rpm -q kio kio-extras5 baloo5-kioslaves

Maybe they are incompatible…

Also check whether some files are missing:

rpm -V kio kio-extras5 baloo5-kioslaves

No output means that everything is ok.

And please try with a fresh user account.
That should show whether it’s an installation issue or some problem with your user settings. (you could try to delete ~/.cache/ though, preferably outside of Plasma5 without any KF5 application running)

#12

Here are the versions:

asoliver@zeon:~> rpm -q kio kio-extras5 baloo5-kioslaves
kio-5.15.0-1.3.x86_64
kio-extras5-15.08.0-7.6.x86_64
baloo5-kioslaves-5.15.0-1.1.x86_64
asoliver@zeon:~> rpm -V kio kio-extras5 baloo5-kioslaves
asoliver@zeon:~>

Also, I logged off and rm -Rf ~/.cache/

It didn’t help. I’ll try setting up a new user next.

#13

I created a new user. I started dolphin with that new user, and it shows the same error. So it’s system related.

#14

i have the issue too.

and i can’t find method solve it. i will focus on it.

#15

What worked for me is starting dolphin using:
dbus-launch dolphin

#16

Shouldn’t be necessary if you run dolphin as the logged-in user.
If you switch to a different user (via su e.g.), then this helps (and even is necessary), yes.

Btw, there is a known bug which causes a similar error message, fixed in KDE Frameworks 5.17.0.
An update will be released for Leap too, but I don’t know yet when.
See https://bugzilla.opensuse.org/show_bug.cgi?id=924764

I somehow suspect that at least Leguan might have suffered from this.
