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

[Richard Leitner - SKIDATA]

Hi Paul,
good to hear I'm not the only one suffering from this issue...
No, I've received no response on the mailing list yet, but maybe someone has a hint for us now?

The only "workaround" I found is to purge the package and afterwards install the new version.
I know this is a really dirty workaround, but it's the only "solution" I found.

Have you discovered any other workarounds, Paul?

regards
Richard

My "workaround" was a little less drastic than yours. (grin)

Before upgrading to the new package via 'dpkg -i', I would edit the postrm script in /var/lib/dpkg/info/<pkg-name>,postrm, adding the "-f" argument to "force" the symlink removal, as suggested by the error message.

Then the upgrade install works correctly. (With only a warning from the postrm script of the previous package.)

I believe that the issue is that when installing a package over an earlier release, dpkg performs the following steps:

1) Extract control files of new package
2) Execute "prerm" script of previous package if applicable.
3) Execute "preinst" script of new package.
4) Unpack new files and backup old files.
5) Execute "postrm" script of previous package if applicable.
6) Configure the package

When installing a newer version of the package, the "postrm" in step 5 fails, because the initscript from the new package is extracted in step 4, and update-rc.d w/o the "-f" argument exits with a non-zero return code.

I would argue that the "updatercd_postrm()" stanza in the update-rc.d.bbclass should include the "-f" flag.
(Anyone on the list want to chime in on this?)

In the meantime, I have added my own "updatercd_postrm()" stanza in the .bbappend file for the package I'm having issues with, which overrides the one provided by update-rc.d.bbclass.

updatercd_postrm() {
update-rc.d $D -f ${INITSCRIPT_NAME} remove
}

Hi Paul,
thank you for that hint and description of your workaround!
Looks like you've invested a little bit more time into working around this issue than me :-)

I've added "-f" to the update-rc.d.bbclass and now it's working like a charm:

diff --git a/meta/classes/update-rc.d.bbclass b/meta/classes/update-rc.d.bbclass
index d8cc342..dbb5781 100644
--- a/meta/classes/update-rc.d.bbclass
+++ b/meta/classes/update-rc.d.bbclass
@@ -33,7 +33,7 @@ updatercd_postrm() {
if test "$D" != ""; then
OPT="-f -r $D"
else
- OPT=""
+ OPT="-f"
fi
if type update-rc.d >/dev/null 2>/dev/null; then
update-rc.d $OPT ${INITSCRIPT_NAME} remove


Nonetheless, I think there have to be a "cleaner" way to solve this issue than forcing the update-rc.d.
Maybe someone else has an idea how to solve this problem?

regards,
Richard
