Comment 1 for bug 1783597

Given that the snaps are located in /var/lib/snapd and we currently allocate free space to download debs in /var/cache/apt/archives and that it is a corner case for those to not be the same mount point it is likely that the space allocated for /var/cache/apt/archives would be enough free space. However, the release upgrader doesn't currently clean up the download .debs at all let alone before installing the snaps. So one solution would be to have the release upgrader clean up after itself.
