This may be a duplicate of https://bugs.launchpad.net/bugs/1673247

This looks like the important part:

Настраивается пакет snapd (2.25~14.04) …
Устанавливается новая версия файла настройки /etc/apparmor.d/usr.lib.snapd.snap-confine …
Failed to execute operation: No such file or directory

dpkg: зависимости пакетов не позволяют настроить пакет snap-confine:

  Пакет snapd пока не настроен.

Thanks

I also added apport because this has some python 2 -> python 3 bugs in the hook errors.

Thanks

I suspect you've been able to resolve this, sorry we never got back to you about it.

I'm closing it as "Won't fix", because we didn't do anything about this, but if you're still stuck there's probably a cause for this that isn't necessarily snapd itself and we can probably figure it out.

Again, sorry.
