I run Ubuntu 16.04 but never installed any snap packages, at least not that I would know of any.
Here are my slowest processes at boot:
$ systemd-analyze blame | head 9.057s snapd.refresh.service 5.058s NetworkManager-wait-online.service 1.126s dev-sdb5.device 822ms storage.mount 804ms data.mount 397ms gpu-manager.service 390ms apt-daily.service 363ms systemd-rfkill.service 334ms systemd-fsck@dev-disk-by\x2duuid-B023\x2d3905.service 251ms accounts-daemon.service
snapd.refresh.service is taking a huge amount of time compared to the rest, especially as I have no need for snaps anyway.
How can I disable all snap related stuff to speed my boot time up?
