Extremely slow seeding


If you take the latest live-server bionic installer at http://cdimage.ubuntu.com/ubuntu-server/bionic/daily-live/current/bionic-live-server-amd64.iso and boot it in a VM, the boot is incredibly slow. systemd-analyze blame points the blame squarely at seeding the snaps:

ubuntu-server@ubuntu-server:~$ systemd-analyze blame
     4min 5.272s snapd.seeded.service
    1min 35.377s snapd.hold.service
         40.861s dev-sr0.device
         38.600s dev-loop3.device
         37.384s dev-loop0.device

snap changes says this

ubuntu-server@ubuntu-server:~$ snap changes
ID   Status  Spawn                 Ready                 Summary
1    Done    2018-06-13T01:47:31Z  2018-06-13T01:48:58Z  Change configuration of "core" snap
2    Done    2018-06-13T01:48:58Z  2018-06-13T01:51:27Z  Initialize system state
3    Done    2018-06-13T01:48:58Z  2018-06-13T01:49:09Z  Initialize device

and for good measure, here’s snap version:

ubuntu-server@ubuntu-server:~$ snap version
snap    2.32.9+18.04
snapd   2.32.9+18.04
series  16
ubuntu  18.04
kernel  4.15.0-23-generic

Is this some kind of known problem? Is there an ETA on a fix?


snap tasks 2 would have been useful there


I just downloaded the above image (2018-05-29 08:19) and booted it using kvm -m 1500 -snapshot bionic-live-server-amd64.iso and once I got a shell ran systemd-analyze blame | head:

         14.000s snapd.seeded.service
          7.313s console-setup.service
          6.829s dev-sda.device
          6.323s dev-loop0.device
          6.303s snapd.hold.service
          5.614s dev-loop2.device
          5.489s dev-loop3.device
          4.129s networkd-dispatcher.service
          3.414s lxd-containers.service
          2.484s pollinate.service

Any hints what I am missing to reproduce this issue? The output of snap version is the same as for you.


Could it be related to the speed of the CDN when accessed from NZ?


Well aggravatingly in some ways, I rebooted my laptop and the problem went away. Confusing and annoying, but probably not snapd’s fault! Sorry for the noise.
