I was able to reproduce the issue with the following:
lxc launch images:ubuntu/focal test-apache2 lxc exec test-apache2 bash
apt update && apt dist-upgrade -y apt install ubuntu-release-upgrader-core apport pciutils apache2 javascript-common -y rm /etc/apache2/conf-available/javascript-common.conf do-release-upgrade
Miguel and others affected by this issue, do you know if you deleted javascript-common.conf at some point in the past?
