3) What you expected to happen : To work properly.
4) What happened instead : Dont work properly, they say "Could not configure for running; got 3 failure(s)"

[arno_b (arno.b)]

I have the same problem on Intrepid.

[juancarlospaco (juancarlospaco)]

Im gonna try to download the .tar.gz sources and (voy a bajar los .tar.gz y hacer) :
./configure
dh_make
sudo checkinstall

To Temporary solution (como solucion temporal).
Can i send this like a Patch...?

[Andreas Roth (aroth)]

Same problem with version 0.24.5-2 from jaunty.

[Bjørn Dyresen (bjorn-dyresen)]

I can confirm this on intrepid. For me puppet runs, but I get the same warnings. The problem seem to be correlated to the symlink /usr/lib/ruby/1.8/lib/xmlsimple.rb => ../xmlsimple.rb

dpkg -S dpkg -S xmlsimple.rb returns:

libxml-simple-ruby: /usr/lib/ruby/1.8/lib/xmlsimple.rb
libxml-simple-ruby: /usr/lib/ruby/1.8/xmlsimple.rb

Seems like some things are getting loaded twice, and hence the warning.

Bugs in the configuration management is a serious thing for people running more than a few handfulls of servers. If Ubuntu wants to be a serious server distro then issues like this needs to be solved.

[Thom May (thombot)]

Can you please run 'puppetmasterd --debug --trace' and paste the output? I'd be surprised if the xmlsimple issue was the actual cause of any crash, and indeed from the above message it's not clear that puppetmaster has actually crashed.
If all this is is just a warning, this is a purely cosmetic issue, and I'll reassign the bug to libxml-simple-ruby.

[Andreas Roth (aroth)]

Here is the output of 'puppetmasterd --debug --trace' of the jaunty puppetmaster:
/usr/lib/ruby/1.8/xmlsimple.rb:275: warning: already initialized constant KNOWN_OPTIONS
/usr/lib/ruby/1.8/xmlsimple.rb:280: warning: already initialized constant DEF_KEY_ATTRIBUTES

/usr/lib/ruby/1.8/xmlsimple.rb:282: warning: already initialized constant DEF_CONTENT_KEY

/usr/lib/ruby/1.8/xmlsimple.rb:287: warning: already initialized constant DEF_KEY_TO_SYMBOL

The puppetmaster does not crash, but it issues these warning on every startup and it looks very bad.

[Thom May (thombot)]

looks like this was a result of http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=491730

[Bryan McLellan (btm)]

Debian bug has been confirmed and split into a libxml-simple-ruby and a rails bug.

[Ryan Niebur (ryan52)]

fixed

[Katherine Rossiter (signe)]

If fixes are released, why aren't they released? It's certainly not fixed in jaunty.

[Ryan Niebur (ryan52)]

it's in karmic.

see the changelog:
http://changelogs.ubuntu.com/changelogs/pool/universe/libx/libxml-simple-ruby/libxml-simple-ruby_1.0.12-1/changelog

and the debian bug it points to:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=514581

[Katherine Rossiter (signe)]

Your comment is the first that mentions karmic anywhere. It's not listed in the changelog, and it's definitely not listed on either of the debian bugs.

It was reported against Intrepid, it still effects Jaunty, and it won't be fixed until Karmic?

[Ryan Niebur (ryan52)]

ok, sorry for not being verbose enough, but you could have checked which ubuntu versions had new uploads of libxml-simple-ruby, and the changelog clearly explained that it fixes this bug.

anyway, I don't know if it will be fixed in Intrepid, or Jaunty, or anything older, but it is fixed for Karmic. I don't contribute to directly to Ubuntu, so I won't be of any help with SRUs/backports. sorry.

[Ryan Niebur (ryan52)]

and looking at https://wiki.ubuntu.com/StableReleaseUpdates#When, it looks like this doesn't warrant a SRU anyway. if you want it fixed on an older version, you can probably just download the .deb from karmic and "dpkg -i" it.

[Pierre-Yves Ritschard (pyr-spootnik)]

Just for the record, changing '/usr/lib/ruby-1.8/lib/xmlsimple.rb' to only read: require 'xmlsimple' fixes the issue for me in jaunty.

[Ryan Niebur (ryan52)]

yes, and that's the change that happened for karmic.
