When removing systemd services, dh_installsystemd has no idea about services present in the older versions that been removed. So, it generates no handling scripts for those services. No convenience methods exist too. dh_installsystemd uses deb-systemd-helper which maintains state files in /var/lib/systemd/deb-systemd-helper-enabled/*.dsh-also. These files need to removed apart from symlinks created in /etc/systemd/system enable services are enabled. If the service/timer is currently running, stop it too. Use deb-systemd-helper and deb-systemd-invoke to achieve this. Closes: #1835 Tests performed: - Install a freedombox version older than 20.5. Upgrade to 20.5. Notice the incorrect symlink /etc/systemd/system/multi-user.target.wants/freedombox-setup-repositories.timer and also the state file /var/lib/systemd/deb-systemd-helper-enabled/freedombox-setup-repositories.timer.dsh-also Then upgrade to a .deb packages built with the patch. The two files will be removed. No extra messages are warnings are printed during package upgrade. - Install a freedombox version older than 20.5. Upgrade to .deb packages built with this patch. Notice the same results. Signed-off-by: Sunil Mohan Adapa <sunil@medhas.org> Reviewed-by: James Valleroy <jvalleroy@mailbox.org>
