    [Post-Install] Missing libKF6NotifyConfig.so causes multiple applications to fail on startup

    Fresh install on a clean drive. I go to open Konsole and it immediately crashes. Checking the system log, I see the following error message.

    Code:
    /usr/bin/konsole: error while loading shared libraries: libKF6NotifyConfig.so.6: cannot open shared object file: No such file or directory​
    Because of this, I'm unable to open Konsole or Yakuake or any shell (other than tty with ctrl + alt + f3, which is a hassle). Couldn't find any mention of this elsewhere online, so here I am

    Please help!

    Good news, everyone! I was able to resolve this issue with a reinstall of libkf6notifyconfig6.

    Code:
    sudo apt reinstall libkf6notifyconfig6
    Not sure what caused that install to fail in the first place, but glad it's a simple solution.

      I have 25.04 (x11) and Konsole works well. Anyway you can replace Konsole with Qterminal (qt based):
      Code:
      sudo apt install qterminal

      Kubuntu 24.04 'Noble Numbat'

        Thanks for the suggestion, looks like qterminal works as a workaround. Still weird that other terminals have this issue.

          Check that you have libkf6notifyconfig6 installed, this is the package that is supposed to supply the missing file from the error.

              Also noticed another symptom: the System Settings -> Accessibility page (/usr/lib/x86_64-linux-gnu/qt6/plugins/plasma/kcms/systemsettings/kcm_access.so) won't load, either, due to the libFS. I don't need this feature, personally, but I imagine that might be an issue for others.

                  Found a similar error on launching Spectacle, but for a different package:

                  Code:
                  /usr/bin/spectacle: error while loading shared libraries: libKF6PrisonScanner.so.6: cannot open shared object file: No such file or directory
                  Was able to fix with a reinstall of package libKF6PrisonScanner6.
