Default applications not working

[mortal urchin]

Lately whenever I try to open a file by double clicking it in Dolphin, it asks me what program I want to use--see attached image. Selecting a program and checking the "remember" box opens the file correctly, but the application is not remembered the next time I try to open it. My ~/.config/mimeapps.list has the correct default applications, but they are not being used. Does anyone know what might be causing this?

On line 26 of mimeapps.list you can see that the default should be feh, but it asks me what I want to use every time.

@mortal urchin pacman -Q feh

[mortal urchin]

❯ pacman -Q feh
feh 3.10.2-1

not just a feh issue, its all my default apps

pdfs should open in firefox but don't, mp4 should open in vlc but don't, etc

I posted solution to this few days ago

There is three possible sol to this -

1. check weather you have kservice5 installed or not by pacman -Q | grep 'kservice5'

If not present then install it

2. see after running dolphin in cmmd line, if you get this type of error (Failed to create wl_display (No such file or directory)
   qt.qpa.plugin: Could not load the Qt platform plugin "wayland" in "" even though it was found.) then the possible sol is this = sudo ln -s /etc/xdg/menus/plasma-applications.menu /etc/xdg/menus/applications.menu

3. Run this -
   kbuildsycoca6 --noincremental
   If it does print this output -> "applications.menu" not found in QList("~/.config/menus", "/etc/xdg/menus"), you will need to get this file.
   To get the applications.menu file, install this package

sudo pacman -Sy archlinux-xdg-menu
Then run this command to generate the file

sudo update-desktop-database
As the file name differs you need to change the file name

cd /etc/xdg/menus

ls
expected output -> "arch-applications.menu"

sudo mv arch-applications.menu applications.menu
Then run again this command and it should work fine

kbuildsycoca6 --noincremental

I know that bro

You know what y flag do, you just know don't ever use this that bla bla, but why it is for then

sudo pacman -Sy archlinux-xdg-menu, -Sy flag is used for synchronizes the package databases. If there is no any conflicts or dependencies requiring a system-wide update, using pacman -Sy followed by the installation or upgrade of specific packages can be acceptable.

This is dolphin issue. not image viewer issue

[mortal urchin]

when would this error occur? right after running dolphin?

oh i see im getting a KSycoca error so im probably in the 3rd case

@ionic stirrup yep, solution 3 worked perfectly! thanks a ton for your help!
