Comment 4 for bug 1773515

I do 99% of my package management with apt-get so it was removed via the command "sudo apt-get remove snapd"

From dkpg.log from just either side of the last mentions of snapd
2018-05-16 13:29:33 startup packages remove
2018-05-16 13:29:33 status installed snapd:amd64 2.32.8+18.04
2018-05-16 13:29:33 remove snapd:amd64 2.32.8+18.04 <none>

2018-05-16 13:29:33 status half-installed snapd:amd64 2.32.8+18.04

2018-05-16 13:29:36 startup packages configure
2018-05-16 13:29:36 trigproc man-db:amd64 2.8.3-2 <none>
2018-05-16 13:29:36 status half-configured man-db:amd64 2.8.3-2
2018-05-16 13:29:37 status installed man-db:amd64 2.8.3-2

apt/history.log gives this date (which time seems to coincide with the finish of the process, not the issue of the command, comparing to the above.)
Start-Date: 2018-05-16 13:29:33
Commandline: apt-get remove snapd
Requested-By: me (1000)
Remove: snapd:amd64 (2.32.8+18.04)
End-Date: 2018-05-16 13:29:37

apt/term.log from the system upgrade and then remove snapd.
