After upgrading to Linux 18.04 my system boot up has become really very slow. I tried to find the reason for it using the systemd-analyze blame and it showed me the below results:

    45.857s systemd-journal-flush.service
     44.055s dev-mapper-ubuntu\x2d\x2dvg\x2droot.device
     39.145s keyboard-setup.service
     35.135s lvm2-monitor.service
     32.417s systemd-udevd.service
     26.688s plymouth-quit-wait.service
     11.402s NetworkManager-wait-online.service
     10.243s mysql.service
      9.523s plymouth-start.service
      8.152s snapd.service
      5.907s NetworkManager.service
      5.526s networkd-dispatcher.service
      5.369s bolt.service
      5.047s udisks2.service
      3.171s postfix@-.service
      3.146s networking.service
      2.923s fwupd.service
      2.889s ModemManager.service
      2.867s wpa_supplicant.service
      2.840s thermald.service
      2.678s accounts-daemon.service
      2.555s gpu-manager.service
      2.434s rsyslog.service

Is there any way to enhance the system boot up process as the boot process has deteriorated from seconds to minutes ?

  • That does not look like the complete output of 'blame'. Without complete information, you may get bad advice. Please edit your question to include the complete output of systemd-analyze critical-chain. It's more useful than 'blame' – user535733 Dec 24 '18 at 16:16
  • My situation may be different than yours, but you might be able to eliminate some services if you are not using them: NetworkManager-wait-online.service waits for the network to be active for example, and plymouth-quit-wait.service can be bypassed by not using the splash setting in grub. – Charles Green Dec 24 '18 at 16:19

  • Please don't ask the same question twice. Please delete one or the other. Thanks! – heynnema Dec 24 '18 at 21:03
