<p dir="ltr">I'll ask them next time to update snapd through apt and reinstall our snap and see what happens.</p>
<p dir="ltr">Is there a fall back variable we can use for older versions? Or a specific version of snap / snapd we should tell them they need?</p>

<p dir="ltr" class="gmail_msg">The most likely cause is, as you suspected, an out of date snapd. SNAP_COMMON was introduced some time after 16.04 (don't have exact version at hand right now).</p>
<p dir="ltr" class="gmail_msg">With recent versions of snapd, the running infrastructure was significantly improved and simplified compared to 16.04 pristine, so it seems less likely to be a problem if up-to-date.</p>

This seems like for some reason SNAP_COMMON isn't getting set.
