〖linux〗 kill Kubuntu annoying software upgrade tip "Update Notification daemon", Your should Update:

Kubuntu is good to use, but the upgrade prompt is too annoying, when the boot always display the following screen:

　　

Use the system Load Indicator (sudo apt-get install indicator-multiload) to view this interface, its process name is NOTIFY-OSD;

Use Locate-b-R notify-osd to locate executable files and find suspicious binary files/usr/lib/x86_64-linux-gnu/notify-osd;

Further using FILE/USR/LIB/X86_64-LINUX-GNU/NOTIFY-OSD, make sure that it is a binary executable file:

file /usr/lib/x86_64-linux-gnu/notify-osd-bit LSB  executable, x86-  1for2.6. buildid[sha1]=9c2f2cba7666738e83360a7e032be135eb3af5a8, stripped

The executable permission is removed by sudo chmod-x/usr/lib/x86_64-linux-gnu/notify-osd;

Unfortunately, there is another more ugly cue box (forgotten) ......

The Final Solution:

Once again through the System Load indicator location, found that the root cause is the KNOTIFY4 process;

The executable file that locates it is/usr/bin/knotify4, and it can be disabled by the command line:

　　sudo chmod-x/usr/bin/knotify4

Well, since then Kubuntu desktop is much quieter;

Note that disabling/USR/BIN/KNOTIFY4 does not affect the use of notify-send;

About the role of the Knoity program: https://docs.kde.org/stable/en/kdeaccessibility/jovie/knotify.html

For me, Knotify4 its reminders will make me feel very annoying, in addition, it also very eat memory (eating memories) ...
