[yocto] Errors with update-rc.d: /etc/init.d/XXX exists during rc.d purge (use -f to force)

[Richard Leitner - SKIDATA]

Hi,
I have problems with the update-rc.d class in my recipes.

When I want to update a package which inherits update-rc.d (in my case samba) using dpkg -i I get the following error:
>root at host:~# dpkg -i /media/USBSTICK/samba-ads_3.5.22-r4_armel.deb 
>(Reading database ... 11931 files and directories currently installed.)
>Preparing to replace samba-ads 3.5.22-r3 (using .../samba-ads_3.5.22-r4_armel.deb) ...

When I afterwards want to remove/purge the package it fails with the following message:
>root at host:~# dpkg -P samba-ads
>dpkg: error processing samba-ads (--purge):
> Package is in a very bad inconsistent state - you should
> reinstall it before attempting a removal.

The only way how to fix that problem is to manually remove the initscript and then install the update:
>root at 000C320C08C0:~# rm /etc/init.d/samba 
>root at 000C320C08C0:~# dpkg -i /media/USBSTICK/samba-ads_3.5.22-r4_armel.deb 
>(Reading database ... 11931 files and directories currently installed.)

The update-rc.d part of my recipe is shown below.
>inherit autotools update-rc.d
>...
>INITSCRIPT_NAME = "samba"
>INITSCRIPT_PARAMS = "defaults"
>...
>do_install_append() {
>	...
>	install -D -m 755 ${WORKDIR}/init ${D}${sysconfdir}/init.d/samba
>	...
>}

Does anybody have an idea how to fix that issue? Would be really great!

Thank you!
