Public bug reported:
[Impact]
Upgrading apt version of lxd to snap version during do-release-upgrade
failed.
I attempted to update my ubuntu server 18.04 system to 18.10 as follows:
apt update
apt dist-upgrade -y
apt autoremove -y
do-release-upgrade
I have an existing LXD installed via apt, and running containers.
It asked me which snap LXD to upgrade to, and I selected "latest".
Console log:

There also appears to be a secondary bug in the error report collection
software, causing it to process an illegal UTF-8 sequence:

I'm afraid I don't know which software package this second error falls
under.
[Test Case]
I'm not sure about this, but I think it may have to do with me already
bind-mounting /var/lib/lxd off the boot drive because it's too small to
support the data (using https://github.com/kstenerud/ubuntu-dev-
installer/blob/master/map-vm-paths.sh). The exact sequence of commands I
used to trigger the bug are:
apt update
apt dist-upgrade -y
apt autoremove -y
do-release-upgrade
[Regression Potential]
