This bug was fixed in the package guile-2.2 - 2.2.3+1-3ubuntu0.1
--------------- guile-2.2 (2.2.3+1-3ubuntu0.1) bionic; urgency=medium
* Convert triggers to noawait (LP: #1780996) (Closes: #903915) - the trigger is supposed to register slib with guile-2.0 but the registration is a no-op, so it's completely safe to make it noawait.
