According to https://bugs.kde.org/show_bug.cgi?id=358359 the fix is included in upstream 5.5.5 release scheduled for today.
According to https://askubuntu.com/questions/230553/how-to-prevent-so- many-instances-of-apt-check-running a similar issue has been around for years. Perhaps the original script should be fixed as well before it happens again. For now, I run apt-get while monitoring htop and if I see apt-check going out of control I pkill it. I hope a fix will be backported to 15.10 ASAP. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1540830 Title: After Plasma 5.5.3 - apt-check causes massive load / creates 100's of processes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-notifier/+bug/1540830/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
