salt: pkg.installed does not seem to refresh the repo database, no matter what

Description of Issue/Question

With the following state file

install:
  pkg.installed:
    - name: some-packagename
    - refresh: True

both salt-ssh, and regular salt fail to call apt-get update (I’m expecting it to be called, based on https://docs.saltstack.com/en/latest/ref/states/all/salt.states.pkg.html#salt.states.pkg.installed) on an Ubuntu system (really doubt this is ubuntu-specific, though). This is deduced by me simply by looking at /var/cache/apt/lists, and noting that no new files are created for a new repo I’ve got in /etc/apt/sources.list.d (running apt-get update manually creates these files though).

Setup

See SLS file above (the - refresh: True line can be removed as well, and the effect will still be the same). Create any valid file in /var/lib/apt/sources.list.d

Steps to Reproduce Issue

See description above.
