dpkg: warning: --compare-versions used with obsolete relation operator '>'

[dino99]

This is what i've seen while upgrading to systemd 223-1ubuntu1:

Processing triggers for systemd (222-2ubuntu1) ...
Processing triggers for initramfs-tools (0.103ubuntu16) ...

Status changed to 'Confirmed' because the bug affects multiple users.

Today systemd has been upgraded to 224-2ubuntu2, and the error reported here has not been seen that time, nor logged.
So it seems a transitional issue that is now gone. Setting that report as 'incomplete' to start the countdown close timer.

This has probably solved this issue:

dpkg (1.18.2ubuntu1) wily; urgency=medium

  * Merge with Debian unstable, bringing in a whole host of new bugfixes.

Can you please run

  grep -r 'compare-version.*>' /var/lib/dpkg/info/

and copy&paste the output here? There is no hit on my current wily system, but perhaps you have some "weird" initramfs-tools version?

[dino99 (9d9)]

Here is the output:

 grep -r 'compare-version.*>' /var/lib/dpkg/info/

/var/lib/dpkg/info/gparted.postinst:if [ "$1" = "configure" ] && dpkg --compare-versions "$2" ge "0.3.9-1" && dpkg --compare-versions "$2" lt "0.3.9-3" && [ -x "`which scrollkeeper-rebuilddb 2>/dev/null`" ]; then
/var/lib/dpkg/info/cups-daemon.postinst: if dpkg --compare-versions "$2" le "1.7.1-9~" && [ -x "`which logrotate 2>/dev/null`" ]; then

note: initramfs-tools is 0.120ubuntu3 (as expected)

[Martin Pitt (pitti)]

Hm, no hits then. If you can't reproduce this any more, then I figure the package which used the obsolete > operator has been upgraded away and got fixed?

If you can still find it (using the grep), please reopen and reassign to that package. I close this for now as we don't have any handle whose fault that was. Thanks!
