Public bug reported: When I try to install a new package on one of my compute nodes which are running one nice-0 task per hyperthread, there is an extremely long delay at the end of installation as apt-check is running at nice 19 and getting almost no cycles. Renicing it to -5 resolves the problem at once.
It is not reasonable to make a human who you know to be sitting at the console wait for a task running at nice 19 on a busy machine to finish, especially if you're holding the dpkg lock the whole time. This is with 16.04.4 ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1781772 Title: apt-get update runs apt-check at nice 19 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1781772/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
