Package: guile-libs Severity: normal slib does not Depend on guile-libs, and I don't think it makes sense to add a Depends, so the trigger should be interest-noawait. (Triggering packages must Depend on the packages they are triggering otherwise ordering can be wrong, and installation can break).
Now, there's also no point to not configure slib until guile-libs is triggered. It's enough to use noawait and thus only put guile-libs in the triggers-pending state, and it will be configured at the end of the apt run. Assuming a package wants to use guile with slib in its postinst, the package will need to Depend on both of them anyway, and that ensures proper ordering. -- System Information: Debian Release: buster/sid APT prefers cosmic APT policy: (500, 'cosmic'), (100, 'cosmic-proposed') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.15.0-23-generic (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled -- debian developer - deb.li/jak | jak-linux.org - free software dev ubuntu core developer i speak de, en
