Description Marja Van Waes 2013-06-29 21:38:37 CEST

urpmi doesn't uninstall foo if it is obsoleted with "Obsoletes:	foo <= [last version]"

It works fine if it is obsoleted with "Obsoletes: foo < [last version + 1]"

I'm saying this in general, because wally reported having seen this, too.

urpmi bar

With packages built from 
(1) http://waesvanm.home.xs4all.nl/Packaging/Bug10659/ttx.spec
and 
(2) http://waesvanm.home.xs4all.nl/Packaging/ttx.spec

"urpmi ttx-0.0.2-1.mga4.<ARCH>.rpm" does not uninstall ttb-1.0.1-2.mga3.noarch if there is 
(1) "Obsoletes:	ttb <= 1.0.1-2"
in the spec file

however 
(2) "Obsoletes:	ttb < 1.0.1-3"
works fine, ttb-1.0.1-2.mga3.noarch is uninstalled.

Compare

Created attachment 4181 [details]
Patch for null to test obsoletes

Yes, I can reproduce this.

Used current null pkg to create null2 (see attachment) which should obsolete null less or equal than current version.

Installed null, uploaded null2 to my local repo and used 'urpmi --auto-select', but null2 doesn't get pulled. If I switch '<= 1:10-3' to '< 1:10-4', all works.

Comment 5 Thierry Vignaud 2014-11-24 14:11:48 CET

Well, as far as rpm is concerned, 1.0.1-2 < 1.0.1-2.mga3
Thus "Obsoletes: ttb <= 1.0.1-2" will obvioulsy NOT match the installed package

Status: NEW => RESOLVED
Resolution: (none) => INVALID

Ah, thanks!

Does that also mean that <quote>Also make sure that the Cauldron package has an higher release than the Mageia 3 package.</quote> in https://wiki.mageia.org/en/Mgarepo was (and is) nonsense?

Comment 7 Thierry Vignaud 2014-11-24 20:03:32 CET

No it's not.
But it can be:
- either 1.0.1-2.mga3 < 1.0.1-2.mga4
- or     1.0.1-2.mga3 < 1.0.1-18.mga4

Thanks again, Thierry, I understand now
