KDE application icon not displayed in Ubuntu

  • 772

Some icons are missing from a KDE application (Okular) in Ubuntu.

How could this be fixed?

Opening okular from terminal shows:
android@android:~$ okular
Invalid Context= "Apps" line for icon theme:  "/snap/communitheme/current/share/icons/Suru/256x256@2x/apps/"
Invalid Context= "Mimetypes" line for icon theme:  "/snap/communitheme/current/share/icons/Suru/256x256@2x/mimetypes/"
Invalid Context= "Mimetypes" line for icon theme:  "/snap/communitheme/current/share/icons/Suru/scalable/mimetypes/"
Invalid Context= "Apps" line for icon theme:  "/snap/communitheme/current/share/icons/Suru/256x256@2x/apps/"
Invalid Context= "Mimetypes" line for icon theme:  "/snap/communitheme/current/share/icons/Suru/256x256@2x/mimetypes/"

  1. First install qt5ct:

    sudo apt install qt5ct

    Then run it and choose your preferred icon/theme:

    Finally set QT_QPA_PLATFORMTHEME to qt5ct in your .profile:

    echo 'export QT_QPA_PLATFORMTHEME=qt5ct' >> $HOME/.profile

    Re-login and it should fix the issue.
