2016-01-08 Thread Launchpad Bug Tracker 
This bug was fixed in the package lubuntu-artwork - 0.59

---
lubuntu-artwork (0.59) xenial; urgency=medium

  * plymouth theme: don't use a Break but a versioned dep to avoid end up
unconfigured during wily -> xenial upgrade. wily's prerm is broken and
doesn't handle deconfigure action. (LP: #1524480)
  * Fix maintainer scripts to not be restrictive on arguments passed to them
for future upgrades.

Alternatively we could drop the "Breaks: plymouth (<< 0.9.2-3ubuntu1~)"
from plymouth-theme-lubuntu-logo. The "Replaces:" will still work for
upgrades, the only thing that doesn't is a partial downgrade. But we
don't care too much about that I think, it's at least way less important
than ruining a lot of upgrades if SRUs don't get installed before.

2016-01-07 Thread Martin Pitt 
Discussed on IRC some more. Summary:
 - Dropping the Breaks: from the theme packages and using a versioned Depends: 
plymouth is semantically equivalent but should avoid the deconfigure (to be 
confirmed)
 - We should fix all the themes' prerm to accept "deconfigure" to fix future 
upgrades.
 - The above should avoid having to SRU all themes (as this wouldn't guarantee 
successful upgrades).

IRC discussion for the record:

08:15:03 pitti | didrocks: do you know, does that only affect lubuntu-logo 
for some reason, or a gazillion other themes too? I. e. the mutual Breaks:
08:15:16 pitti | mutual Breaks: forces "deconfigure", i. e. I wonder if we 
can avoid that somehow
08:17:07  didrocks | hey pitti! I'm afraid that's pretty much global, indeed
08:17:38  didrocks | pitti: as most of the themes seems to be copy and paste 
and they copied a wrong prerm
08:18:08  didrocks | yeah, the Breaks/Replaces is just about the moving files, 
to ensure we don't end up for partial upgrade with an non working theme
08:18:09 pitti | didrocks: oh, so that's not just plymouth's prerm, but 
*all* prerms of logo packages?
08:18:34  didrocks | pitti: yeah, plymouth prerm is fine (let me confirm in a 
minute), it's the ones in the logo packages for sure at least
08:18:42  didrocks | and most of them are copy/paste :/
08:18:47 pitti | didrocks: so instead of SRUing all logo packages and 
plymouth itseslf, it seems easier to me to just drop the Breaks: of the logo 
packages in xenial?
08:19:18  didrocks | yeah, that would be slightely incorrect, but there is 
nothing else anyway that should call deconfigure on those packages
08:19:21 pitti | didrocks: oh, ok, I misinterpreted the log, it's indeed 
not plymouth itself
08:19:32 pitti | didrocks: right, which is how it got unnoticed for so long
08:19:37  didrocks | we should still fix them in xenial though, so that this 
doesn't happen in the future
08:19:39  didrocks | well, years :p
08:19:52  didrocks | some packages were untouched since 2010/2011…
08:19:55 pitti | didrocks: curiously I had exactly the same case for 
ifupdown and udev two days ago (mutual Breaks:, missing deconfigure in 
udev.prerm)
08:20:22 pitti | didrocks: yes; so my proposal is to fix all the logo 
packages in xenial with (1) teaching prerm about deconfigure, and (2) dropping 
the Breaks: to fix upgrades
08:20:27  didrocks | I don't know why people are doing this *) echo "Call with 
unknown parameter; exit 1
08:20:41 pitti | didrocks: I had that too; I think that was in some 
standard templates
08:20:55 pitti | but that's a bit overzealous indeed
08:20:59  didrocks | pitti: as most cases are empty anyway, I would suggest we 
drop that
08:21:01  didrocks | yeah
08:21:22  didrocks | so yeah, we can workaround and avoid the SRU by removing 
the Breaks
08:21:28  didrocks | (in plymouth)
08:21:36 pitti | didrocks: oh, in plymouth, not in the logo packages?
08:21:45  didrocks | the Breaks in plymouth against logo packages
08:21:46 pitti | didrocks: you should drop it on the side which has the  
Replaces:, not the other one
08:21:58  didrocks | there is no Replaces
08:22:00  didrocks | just Breaks
08:22:25  didrocks | basically, new plymouth needs themes in /usr/share instead 
of /lib
08:22:26 pitti | Replaces: lubuntu-plymouth-theme, plymouth (<< 0.8.1-1~)
08:22:36 pitti | oh, I see, that's much older, not from this transition
08:22:39  didrocks | yeah
08:22:51  didrocks | the breaks is just to ensure we don't install new logo 
without new plymouth
08:22:54  didrocks | and vice-versa
08:23:13 pitti | didrocks: that could also become a versioned depends: on 
the logo (which is simpler)
08:23:33 pitti | i. e. Depends: plymouth + Breaks: plymouth (<< 
0.9.2-3ubuntu1~) == Depends: plymouth (>= 0.9.2-3ubuntu1~)
08:23:46 pitti | (was looking at plymouth-theme-lubuntu-logo)
08:23:54  didrocks | but if you upgrade plymouth alone
08:24:01  didrocks | you are in a "broken" situation
08:24:07  didrocks | (for some definition of broken, for sure ;))
08:24:18 pitti | didrocks: yes, that's why I think we should keep the 
Breaks: on plymouht and drop it from the themes
08:24:46  didrocks | the breaks in plymouth won't force deconfigure in -logo?
08:24:57 pitti | didrocks: only a mutual Breaks: forces that
08:25:07 pitti | didrocks: if it's one-sided, the broken package gets 
upgraded first
08:25:14  didrocks | oh didn't know that, was thinking one way was enough if 
plymouth was going to get configured first
08:25:17  didrocks | ok
08:25:25  didrocks | so apt reorders
08:25:27  didrocks | making sense
08:25:47 pitti | didrocks: but if both packages break each other, there is 
no order which would always be consistant, so apt randomly picks one package, 
deconfigures that, and upgrades both
08:25:48  didrocks | I can handle it then
08:25:53  didrocks | indeed
08:26:11  didrocks | we should maybe at some point scan the archive to see if 
this broken

fixing this probably requires an SRU, to get a fixed version of
plymouth-theme-lubuntu-logo onto the system *before* trying to upgrade
to the new version of plymouth in 16.04.

The error in the logs is:

De-configuring plymouth-theme-lubuntu-logo (0.56) ...
/var/lib/dpkg/info/plymouth-theme-lubuntu-logo.prerm called with unknown 
argument `deconfigure'

This is a grave bug in the plymouth-theme-lubuntu-logo package.
