After upgrading from 17.04 to 18.04 I found bootup to be a little slow. After running systemd-analyze blame I get the following output

     38.090s snapd.seeded.service
     36.432s snapd.service
      6.485s NetworkManager-wait-online.service

       249ms ModemManager.service
       237ms systemd-resolved.service
       232ms systemd-timesyncd.service

What can I do to reduce the bootup time, specifically these snapped services?

    I'd make sure fully updated (sudo apt update && sudo apt upgrade) Then purge snapd (sudo apt purge snapd) After that open Software & Updates > Developer options > enable the proposed repo. Then update sources & install snapd. (sudo apt update && sudo apt install snapd). After it's installed again open Software & Updates & disable the proposed repo, update sources. – doug Jul 4 '18 at 0:57
  • Thanks @doug. The update definitely helped a reducing the startup time to 17 seconds. But it still takes much longer than the 6 seconds for the second process. – Clintus Jul 5 '18 at 2:50
  • Here all the snapd stuff in systemd-analyze blame is completely done by 202ms (i.e snapd.service) , the snapd.seeded.service at 8ms. So NetworkManager-wait-online.service is top shown (at about 6 sec. – doug Jul 5 '18 at 4:59
  • What happens if you install a snap? (assuming you don't have any installed? – doug Jul 5 '18 at 5:07
  • HI doug, I checked again and snapd was done at >200ms. Thanks, I'm not sure if it was the purge or a recent update but network is now theslowest process. Thanks. I did previously try installing hello world snapd package but that didn't help. – Clintus Jul 6 '18 at 8:54

I've had this today with 18.04 too (no upgrade, was fine before today), I've found that moving my mouse/swiping my trackpad constantly on the loading screen speeds loading up by a lot for this issue, though I am unsure why. It goes from >4 min to less than 1 min.
